Question

3) Solve for x:

-5x + 9 = 24
(2 points)


x = (____)

4) Which equation has the solution x = -4? (1 point)
A) -4x + 1 = 5
B) x/3 - 7 = -6
C) 3x + 2 = -10

5) Solve for x:
2/3x - 6 = 10
(2 points)

x = (_____)


6) 3.2x + 12 = 48
(2 points)


x = (_____)

Answer 1

3) -5x + 9 = 24
-5x = 15 → x = -3
x = (-3)

4) Which equation has solution x = -4?
Check C: 3(-4)+2 = -12+2 = -10, so C

5) (2/3)x - 6 = 10
(2/3)x = 16 → x = 16 * (3/2) = 24
x = (24)

6) 3.2x + 12 = 48
3.2x = 36 → x = 36 / 3.2 = 11.25
x = (11.25)
