Question

Solve linear equation 2y+20=2-y. 3y+20=2

Answer 1

y = -6

Explanation:

y is multiplied by 3 and 20 is added to the sum. We undo these operations in reverse order.

First we subtract 20 from both sides of the equation:

3y = -18

Then we divide both sides of the equation by 3 to undo the multiplication.

y = -18/3 = -6

The solution is y = -6.
