8x-16=3x+16 (add 1 and 15)
8x-3x=16+16 (move like terms to one side : Subtract 3x from both sides and add 16 to both
sides
5x=32 (Subtract 3x from 8x, then add 16 to 16)
x=32/5 (divide both sides by 5)
or x=6.4 if you would rather a decimal

1. Distribute 2 to x+6
10+2x+12 = -10
2x+22 = -10
Subtract 22 from both sides
2x=-32
x=-16

2.Distribute 8 to x-2 and 3 to x+5
8x-16 = 3x+15+1
Subtract 3x from both sides and add 16 to both too
5x=32
x=32/5 (32 divided by 5)

distribute the 2 into the parenthesis giving you 10+2x+12=-10
then solve for x by subtracting over the 10 and 12
2x=-10-10-12
2x=-32
x=-32/2
x=-16

same with number 2. distribute into the parenthesis'
8x-16=3x+15+1
8x-3x=16+16
5x=32
x=32/5

-

1) 10 + 2(x+6) = -10
10 + 2x + 12 = -10
2x + 22 = -10
x + 11 = -5
x = -16
2) 8(x-2) = 3(x+5) + 1
8x - 16 = 3x + 15 +1
5x = 32
x = 32/5
