Question

1.x/3.5+9=3.5+9 2.4(3x+2)-22.4

Answer 1

1.x/3.5+9=3.5+9

x/3.5=3.5

x =12.25

2.4(3x+2)=22.4

12x+8=22.4

12x=14.4

x=1.2

3.x+2x+10=280

3x=270

x=90

4.x+9=3x-4-7

-2x=-20

x=10

5.4x-20=2x-8

2x=12

x=6

6.60-7x=26x-35

-33x=-95

x=95/33

7.43-0.4x=26.2+x

-1.4x=-16.8

x=12

8.3x+2=2(x+11)

x=20

9.3(x+2)-1=5-2(x-2)

3x+6-1=5-2x+4

5x=4

x=4/5

10.6(3x-2)=1+4(4x+3)

18x-12=1+16x+12

2x=25

x=25/2

11.x+10=(x-120)*3.5

x+10=3.5x-420

-2.5x=-430

x=172

12.26-3(2x-5)=4x-11

26-6x+15=4x-11

-10x=-52

x=5.2

13.12+5(3x-4)=24-2(x-1)

12+15x-60=24-2x+2

17x=74

x=74/17

14.4x+8=2*(x+16)

4x+8=2x+32

2x=24

x=12

15.7x-535=(x-3)6

7x-535=6x-18

x=517
