Question

-8a-5=-7a+3 help someone
​

Answer 1

Answer: a = -8

Explanation:

Given

-8a - 5 = -7a + 3

Subtract 3 on both sides

-8a - 5 - 3 = -7a + 3 - 3

-8a - 8 = -7a

Add 8a on both sides

-8a - 8 + 8a = -7a + 8a

a = -8

Hope this helps!! :)

Please let me know if you have any questions

Answer 2

a = -8

Explanation:

-8a-5=-7a+3 Add 5 to both sides.

- 8a = - 7a + 3 + 5 Combine

-8a = - 7a + 8 Add 7a to both sides

-8a + 7a = 8 Combine

-a = 8 Multiply by - 1

a = - 8

When you get a weird number like this, you should check it.

LHS = -8(-8) - 5

LHS = 64 - 5

LHS = 59

RHS = -(7*-8) + 3

RHS = -(-56) + 3

RHS = 56 + 3

RHS = 59

So a = - 8 must be right.
