2x - 2y = -12
- 2y = -2x - 12
y = x + 6

4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9

y = -9 + 6
y = -3

(-9 , -3) is the solution

What is the solution to the equation 6y –2(y + 1) = 3(y – 2) + 6?
AleksAgata [21]

Answer: y=2

Step-by-step explanation:

Distribute the numbers -2 and 3...

6y-2y-2=3y-6+6

The -6 and 6 cancel each other out...

6y-2y-2=3y

Combine like terms....

4y-2=3y

Move 4y over....

-2=-y

Multiply both sides by -1.....

2=y

That’s your solution! Hope this helps!
