Answer:

-2
24
6
-36

Step-by-step explanation:

Put the numbers in place of the corresponding letter and do the arithmetic.

y -10 = 8 -10 = -2

12 -z = 12 -(-12) = 24

3 -x = 3 -(-3) = 6

z -24 = -12 -24 = -36

Please HELP!!!!!!!!!

Calculate the sum

5x - 10 + 7 = 65 - 20x + 32

Move terms

5x - 3 = 97 - 20x

Collect the like terms and calculate

5x + 20x = 97 +3

Divide both sides by 25

25x = 100

X= 4 ANSWER

I skipped some steps because it would be too long :/

Multiply parenthesis by 8

20x>8(4x - 5) -20

Calculate

20x>32x - 40 - 20

Move variable to the left

20x>32x-60

Collect like terms

20x - 32x > -60

Divide both sides by -12

-12x>-60
