Question

B) 3(x-1) = 12
C) 4(x+5) = 60
D) 5(x-3) = 45
E) 2(x+3) = 18

Me ajudemm no rápido , a conta montada por favor

Answer 1

B) 3(x - 1) = 12

3x + 3 = 12

3x = 12 - 3

3x = 9

x = 9/3

x=3

C) 4 (x + 5) = 60

4x + 20 = 60

4x = 60 - 20

4x = 40

x = 40/4

x = 10

D) 5(x-3) = 45

5x - 15 = 45

5x = 45 + 15

5x = 60

x = 60/5

x = 12

E) 2(x+3) = 18

2x + 6 = 18

2x = 18 - 6

2x = 12

x = 12/2

x = 6
