Question

Solve for y. Simplify your answer as much as possible. 19 = 2y - 15

Answer 1

y=17

Explanation:

19=2y-15

move the variable to the left-hand side and change its sign

-2y+19=-15

move the constant to the right-hand side and change its sign

-2y=-15-19

Calculate the difference

-2y=-34

divide both sides by -2

y=17
