Question

Solve each of the following equations.

a. 5x = –65
b. 40 + x = –5
c. 120 = 6x
d. 6 = z ÷ 14
e. 11y + 20 = 64
f. 6x + 20 = –4
g. 3y – 11 = –32
h. x ÷ 16 = 3

Answer 1

A. -13
B. -45
C. 20
D. 84
E. 4
F. -4
G. -7
H. 48

Answer 2

Answer with Step-by-step explanation:

a. 5x = –65

Dividing both sides by 5, we get

x= -13

b. 40 + x = –5

subtracting 40 on both sides, we get

x= -45

c. 120 = 6x

dividing by 6 on both sides, we get

x= 20

d. 6 = z ÷ 14

Multiplying both sides by 14,we get

z= 84

e. 11y + 20 = 64

11y= 44

y= 4

f. 6x + 20 = –4

6x= -24

x= -4

g. 3y – 11 = –32

3y= -21

y= -7

h. x ÷ 16 = 3

Multiplying both sides by 16,we get

x= 48
