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
