SOLUTION
Write out the equation

The first step in solving this equation is to multiply both sides by 2 this is called
MULTIPLICATION PROPERTY OF EQUALITY
Step1; MUltiply both sides by 2

The next step in solving this equation is to add 7 to both sides of
the equation this is called ADDITION PROPERTY OF EQUALITY
step2: Add 7 to both sides of the equation

Hence the solution to the equation is y=-15
The steps are
Step1; MULTIPLICATION PROPERTY OF EQUALITY
Step2: SIMPLIFYING
Step3: ADDITION PROPERTY OF EQUALITY
Step4: SIMPLIFYING
