To solve for h, we want h to stand alone.  So, in the equation

we need to move the 7.  To move it, we need to cancel it.  We can see that h is being divided by 7.  So, to cancel it, we need to multiply by 7.

If we multiply by 7 on the left side of the equal sign, we need to multiply by 7 on the right side of the equal sign.  So, we get

To solve for b, we want b to stand alone.  So, in the equation

we need to move the 6.  To move it, we need to cancel it.  Right now, b is being multiplied by the 6.  So, to cancel, we need to divide.

If we divide by 6 on the left side of the equal sign, we need to divide by 6 on the right side of the equal sign.  So, we get

To solve for a, we want a to stand alone.  So, in the problem

we need to move the 4.  To move it, we need to cancel it.  Right now, a is being divided by 4.  So, to cancel it, we need to multiply.

If we multiply by 4 on the left side of the equal sign, we need to multiply by 4 on the right side of the equal sign.  So, we get

To solve for x, we want x to stand alone.  In the equation

we need to move the 9.  To move it, we need to cancel it.  We can see x is being divided by 9.  To cancel division, we need to multiply.

If we multiply by 9 on the left side of the equal sign, we need to multiply by 9 on the right side of the equal sign.  So,

To solve for y, we want y to stand alone.  So, in the equation

we want to move the 9.  To move it, we need to cancel it.  Right now, y is being multiplied by 9.  To cancel multiplication, we need to divide.  

If we divide by 9 on the left side of the equal sign, we need to divide by 9 on the right side of the equal sign.  So, we get

To solve for k, we want k to stand alone.  So, in the equation

we want to move the 7.  To move it, we need to cancel it.  Right now, k is being multiplied by 7.  To cancel multiplication, we need to divide.  

If we divide by 7 on the left side of the equal sign, we need to divide by 7 on the right side of the equal sign.  So, we get

To solve for y, we want y to stand alone.  

So, in the equation

we need to move the 8.  To move it, we need to cancel it.  Right now, y is being multiplied by 8.  To cancel, we need to divide by 8.

If we divide by 8 on the left side of the equal sign, we need to divide by 8 on the right side of the equal sign.  So, we get

To solve for h, we want h to stand alone.

So, in the equation

We want to move the 6.  To move it, we need to cancel it.  Right now, h is being divided by 6.  To cancel, we need to multiply by 6.  If we multiply by 6 on the left side of the equal sign, we need to multiply by 6 on the right side of the equal sign.  So,

To answer this, we want to solve for x.  So, we get

To solve for y, we want y to stand alone.  So, we get
