Question

1. 5 (2 + 4) = 35
- 3
5. 0.6x - 1.9 = 0.2x + 0.5
6. 2(3y - 2) – 4(2y - 5) = 9
4. 3x - 2 = x - 3
7. 513 – x) + 1 = 3(x + 4)
8. 7-2(5 - 3x) = 4(x – 3) + 5​

Answer 1

5)0.6x-1.9=0.2x+0.5

0.6x-0.2x=0.5+1.9

0.4x=2.4

x= 2.4/0.4

x= 6

6)2(3y-2) -4(2y-5) =9

6y-4-8y+20=9

-2y+16=9

-2y=9-16

-2y=-7

y=-7/-2

y=7/2

y=3.5

4) 3x-2=x-3

3x-x=-3+2

2x=-1

x=-1/2

x=-0.5

7)(513-x)+1=3(x-4)

513-x+1=3x-12

513+1+12=3x+x

526=4x

x=526/4

x=131.25

8)7-2(5-3x)=4(x-3)+5

7-10+6x=4x-12+5

-3+6x=4x-7

6x-4x=-7+3

2x=-4

x=-4/2

x=-2
