Question

Answer 1

5:

26+4(6x-7)=118

=>4(6x-7)=118-26=92

=>6x-7=23

=>6x=30

=>x=5

6:

\(5\left(7x-32\right)+18=68\)

=>\(5\left(7x-32\right)=50\)

=>7x-32=10

=>7x=42

=>x=6

7: \(112-12:x=109\)

=>12:x=112-109=3

=>x=12/3=4

8: \(2\left(9x+15\right)-24=78\)

=>\(2\left(9x+15\right)=102\)

=>9x+15=51

=>9x=36

=>x=4

9: \(275-6\left(52-3x\right)=71\)

=>\(6\left(52-3x\right)=275-71=204\)

=>\(52-3x=34\)

=>3x=18

=>x=6

14:

\(178-35:x=173\)

=>\(35:x=178-173=5\)

=>x=35/5=7

15:

\(94+162:x=175\)

=>\(162:x=81\)

=>x=162/81=2

16: \(81:x+71=98\)

=>\(81:x=98-71=27\)

=>x=3

17: 58:(x+7)=2

=>x+7=58/2=29

=>x=29-7=22

18: 75:(52-x)=5

=>52-x=15

=>x=52-15=37
