Example Question #51 : Two Step Equations With Integers
Solve:
To isolate the unknown variable, first add three on both sides.
Divide by negative three on both sides.
Example Question #52 : Two Step Equations With Integers
Solve:
In order to solve the equation, we have to isolate the variable. We do this by performing the same operation to either side of the equation.
Add 18 on both sides of the equation.
Divide both sides by six.
The six in the numerator and in the denominator cancel and we are left with,
