Question

b) X-14 = 7
c) x+1=2
d) 2x + 40 = 80
e)5x - 15 = 35
f) x +5 = -10
g) 15 +x = 20
h) 3x - 18 = -36
i) 4x +6 =18​

Answer 1

b) x-14 = 7

x = 7 + 14

x= 21

c) x + 1 = 2

x = 2-1

x=1

d) 2x + 40 = 80

2x = 80 - 40

2x = 40

x= $\frac{40}{2}$

x = 20

e) 5x - 15 = 35

5x = 35 + 15

5x = 50; x= $\frac{50}{5}$

x = 10

f) x + 5 = -10

x = -10 -5

x = -15

g) 15 + x = 20

x = 20 - 15

x = 5

h) 3x - 18 = -36

3x = -36+18

3x = -18

x= $\frac{-18}{3}$

x = -6

i) 4x + 6 = 18

4x = 18 - 6

4x = 12

x = $\frac{12}{4}$

x = 3
