-130 = -5(1 - 5x)
A) (4) B) {-5}
c) {-1} D) (11)

B, -5

Step-by-step explanation:

-130 = -5(1 - 5x)

1) Distribute- multiply -5 by all the numbers in the parentheses, 1 and -5x.

-130 = -5 + 25x

2) Isolate the variable- add 5 on both sides and divide both sides by 25

-125 = 25x

-5 = x

Final B, -5

me! what did you put for this question?

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
