4. For each equation, find a value for x that makes the equation true. Show your work on the next
page.
a.
x=3 = 12
b.
2x + 3 = 20
4
10
C.
d.
- 4x = -24
e.
2(x – 4) = 10
-0.5x + 1.1 = -2.9
f.

A.) x / 3 = 12      > x = 12(3)   > x = 36

B.) 2x + 3 = 20  > 2x = 17 > x = 17/2

C.) 4/3x = 10/3 > x = 10/3 x 3/4 > x = 30/12 = 5/2

D.) -4x = -24 > x = -24/-4 > x = 6

E.) 2(x-4) = 10 > 2x - 8 = 10 > 2x = 18 > x = 9

F.) -0.5x + 1.1 = -2.9 > -0.5x = -4 ---> x = -4 / -0.5 > x = 8

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
