Question

Solve the equation using the addition property of equality. Be sure to check your proposed solution. -7y+5=-8y+2

Answer 1

The answer is:

y = -3

Work/explanation:

Combine like terms on each side:

`\sf{-7y+5=-8y+2}`

`\sf{-7y+8y=2-5}`

Simplify.

`\sf{y=2-5}`

`\sf{y=-3}`

Hence, y = -3.

Answer 2

y = -3

Explanation:

-7y + 5 = -8y + 2

y + 5 = 2

y = -3

Let's Check

-7(-3) + 5 = -8(-3) + 2

21 + 5 = 24 + 2

26 = 26

So, y = 26 is the correct answer.
