Question

3ori(2x-4)+x=27

3+2(x-1)=17
5(x+3)+2(x+3)=56

Answer 1

3(2x-4)+x=276x-12+x=27
7x=27+12
x=39/7

3+2(x-1)=17
3+2x-2=17
2x=17-1
x=16/2
x=8

5(x+3)+2(x+3)=56
5x+15+2x+6=56
7x+21=56
7x=56-21
x=35/7
x=5

Answer 2

3(2x-4)+x=27
6x-12+x=27
7x-12=27
7x=27+12
7x= 39
x= 39: 7 = 5,(5)

3+2x-2=17
3+2x=17+2
3+2x=19
2x=19-3
2x=16
x= 16 :2= 2

5x+15+2x+6=56
5x+15+2x=56-6
5x+15+2x=50
7x+15=50
7x=50-15
7x=35
x=35:7= 5.

Sper ca te-am ajutat ! :)
