Question

3) 5(4 + x) = 7x-2
4) 2(x +3) = 12
5) 5(3x + 2) = 8(9-2x)
6) 38 + 7(x – 3) = 9(x - 1)
7) 2(3x – 7) + 6 = 4x – 3(2- 2x)
8) 11x + 4 = 3(1 – 2x) + 1
9) 7(3x + 2) -5(4x - 3) = 4(x - 2) + 1
10) 2 (x+3) -6 (5+x) = 3x+4​

Answer 1

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

20+5x=7x-2

5x-7x=-2-20

- 2x=-22

X = - 22/-2

X =11

4) 2(x +3) = 12

2x+6 = 12

2x = 12-6

2x=6

X=6/2

X=3

5) 5(3x + 2) = 8(9-2x)

15x+10=72-16x

15x+16x=72-10

31x = 62

X =62/31

X = 2

6) 38 + 7(x – 3) = 9(x - 1)

38+7x-21 = 9x - 9

7x-9x =21-9-38

- 2x = - 8

X = - 8/-2

X = 4

7) 2(3x – 7) + 6 = 4x – 3(2- 2x)

6x - 14+6=4x-6+6x

- 4x=14

X =14/-4

X = - 7

8) 11x + 4 = 3(1 – 2x) + 1

11x+4=3-6x+1

11x +6x =3-4+1

17x = 0

X = 17

9) 7(3x + 2) -5(4x - 3) = 4(x - 2) + 1

21x+14-20x+15=4x-8+1

21x - 20x-4x=20-14-15-8+1

- 3x =12

X = 12/-3

X = - 4

10) 2 (x+3) -6 (5+x) = 3x+4

2x+6-30-6x=3x+4

2x-6x-3x=-6+30-4

- 7x = 20

X = - 20/7
