Question

Solve each equation a. 25-3x=40

b. 1/3(x-10)= -4
What does x equal to for each equation?

Answer 1

a. x equals -5
b. X equals 26/8 (or it could be written as 8 and 2/3, or about 8.6)

Answer 2

a. x = -5

b. x = -2

Explanation:

a.

40=25-3x

40=25-(-15)

x should be -5 for a

b.

-4=1/3(x-10)

-4=1/3(-2-10)

-4=1/3(-12)

x should be -2 for b
