Step 1 add 4x to both side eliminating it from the left side. 7y-4x=28
+4x=+4x
Step 2 doing that the 4x on the left side will go away and the problem should look like
7y=4x+28

Step 3 you need to isolate the y variable by dividing 7 on both sides. 7y/7=4x/7+28/7

The answer should be y=4/7x+4

Answer:

x = -26

Step-by-step explanation:

Multiply both sides by the lowest common multiple of 4 and 3, which is 12.

3(x+2) = 4(x+8)

3x + 6 = 4x + 32 --- distribute the 4 and 3

6 = x + 32 --- subtract 3x from both sides

-26 = x --- subtract 32 from both sides

x = -26
