Question

Match each equation to a step that will help solve the equation.

Eqautions: Numbers:
1) Multiply each side by 5.
2) Multiply each side by -5.
3) Multiply each side by 1/5.
4) Multiply each side by -1/5.
A) 5x= 0.4
B) x/5=8
C) 3 = -x/5
D) 7 = -5x

Answer 1

A) 5x = 0.4 — 3) Multiple by 1/5

B) x/5 = 8 — 1) Multiple by 5

C) 3 = -x/5 — 2) Multiple by -5

D) 7 = -5x — 4) Multiple by -1/5


Step-by-step explanation:

A:
5x = 0.4

5x • 1/5 = 0.4 • 1/5

x = 2/25 or 0.08


B:
x/5 = 8

x/5 • 5 = 8 • 5

x = 40


C:
3 = -x/5

3 • -5 = -x/5 • -5

-15 = x

x = -15


D:
7 = -5x

7 • -1/5 = -5x • -1/5

-7/5 = x

x = -7/5 or -1.4
