Question

Answer 1

1: \(17+3\left(2x+24\right)=107\)

=>\(3\left(2x+24\right)=107-17=90\)

=>2x+24=90/3=30

=>2x=6

=>x=3

2: 2(3x+15)+124=178

=>2(3x+15)=178-124=54

=>3x+15=54/2=27

=>3x=27-15=12

=>x=12/3=4

3: \(27+3\left(17-4x\right)=54\)

=>\(3\left(17-4x\right)=54-27=27\)

=>17-4x=9

=>4x=8

=>x=2

12: 2(11x-42)-18=8

=>2(11x-42)=26

=>11x-42=13

=>11x=42+13=55

=>x=5

11: 119-3(7x-4)=47

=>3(7x-4)=119-47=72

=>7x-4=24

=>7x=28

=>x=4

10: 4(53-5x)-52=80

=>4(53-5x)=80+52=132

=>53-5x=132/4=33

=>5x=53-33=20

=>x=20/5=4
