Question

There very hard to do i try asking my teacher to help me but im still not good at it

Answer 1

The 1st one is y = 11.

The 2nd one is y = 5.

The 3rd one is v = -5.

The 4th one is y = 9.

Explanation:

1) -38 = 7y + 17 - 12y

-38 = -5y + 17

-55 = -5y

11 = y

2) 5y + 6 - 12y = -29

-7y + 6 = -29

-7y = -35

y = 5

3) -12v - 9 + 7v = 26

-5v - 9 = 26

-5v = 35

v = -5

4) -5y + 2(y + 2) = -5

-5y + 4y + 4 = -5

-y + 4 = -5

-y = -9

y = 9
