Question

a)3x-3=x+5

b)9x+1=5x+25

c)6.(x-3)=18

me ajudem por favor

Answer 1

a)
3x - 3 = x + 5
3x - x = 5 + 3
 2x = 8
x = 8/2
x = 4

***************************
b)
9x + 1 = 5x + 25
9x - 5x = 25 - 1
4x = 24
x = 24/4
x = 6

***********************
c)
6.(x - 3) = 18
6x - 18 = 18
6x = 18 + 18
6x = 36
x = 36/6
x = 6
