step 1 Multiplication property of equality Multiplying the second equation by -2 Step 2 Additional property of equality We add the two equations generated in step 1 Step 3 The division property of equality We divide both sides of equation obtained in step 2 by 13 Step 4 Substitution property of equality We substitute the value obtained in step 3 for y in the first equation. Step 5 Simplify
Step 6 Additional property of equality We add +3 on both sides of the equation in order to have an equation with a variable x. Step 7 Division property of equality We divide both sides of the equation obtained to get the value of x
