y = 2
x = 8
Use distributive property at the beginning and isolate the variable.

For the first one:
2 - 8y + 48 = 4y - 70 (multiply term inside the brackets)
-8y - 4y = -70 - 48 (subtract 4y and 48 from each side)
-12y = - 118 (calculate)
12y = 118 (divide by -1 to make positive)
y = 118/12 (now you need to calculate the answer)
Follow the same procedure for the second one.

2- 8y -48 = 4y - 70
-46 = 12y -70
24 = 12y
y = 2
x -2x + 6 = 3x -2x -10
-x + 6 = x - 10
6 = 2x - 10
16 = 2x
x = 8
This really wasn't that hard. It took me about two minutes.

2-8y-48=4y-70
70-46=12y
24=12y
y=2
x-2x+6=3x-2x-10
-3x+6=-x-10
16=2x
x=8

That's cheating. And for copying out your homework for others to answer it, I won't tell you! And I knew the answer.

2-8y-48=4y-70
-46-8y=4y-70'
-12y=-24
-12y/-12=-24/-12
y=2
x-2x+6=3x-2x-10
-x+6=x-10
-2x=-16
-2x/-2=-16/-2
x=8
