Question

f) 4x + 7 - 2x = 10 - 3
g) 2x + 3 = 15
h) 5x - 8 = - 33
i) 8x - 12 = 4x + 12
j) X - 24 = 10
k) x + 8 = 8​

Answer 1

Resposta:

f) 4x + 7 - 2x = 10 - 3

4x -2x = 10 - 3 - 7

2x = 0

x = 0/2 = 0

g) 2x + 3 = 15

2x = 15-3

x = 12/2

x = 6

h) 5x - 8 = - 33

5x = -33 +8

5x = -25

x = -25/5

x = -5

i) 8x - 12 = 4x + 12

8x-4x = 12 + 12

4x = 24

x = 24/4

x = 6

j) X - 24 = 10

x = 10+24

x = 34

k) x + 8 = 8​

x = 8 - 8

x = 0
