Question

calcule a)6x+2=14 b)9x-3=24 c) 10x+5=45 d)10x+5=4x+11

Answer 1

Explicação passo-a-passo:

A)

6x + 2 = 14

6x = 14 — 2

6x = 12

x = 12/6

x = 2

B)

9x — 3 = 24

9x = 24+3

9x = 27

x = 27/9

x = 3

C)

10x + 5 = 45

10x = 45—5

10x = 40

x = 40/10

x = 4

D)

10x + 5 = 4x + 11

10x — 4x = 11—5

6x = 6

x = 6/6

x = 1
