Question

5. Solve the equations :
(1) 4x + 13 = 3x + 15
(2) 9x - 15 = 7x + 1
(3)x + 18 = 2x - 7
(4) 3x + 8 = 4 - 5x
(5) 8x + 4 = 3 (x - 1) + 2
(6) 3x - 10 = 5 (x - 10)​

Answer 1

Answer:

(1) 4x-3x=-13+15

1x+2

x=2

(2)9x-7x=-15+1

2x=-14

x=-14/2

x=-7

x-2x=-18-7

1x=-11

x=-11

Answer 2

✴Answer :

5)

1) 4x+13=3x+15

4x-3x=15-13

=> x = 2

2)9x -15 =7x+1

9x-7x= 1+15

2x = 16

=> x = 8

3) x+18= 2x -7

x-2x=-7-18

-x=-25

=> x =25

4)3x+8= 4-5x

3x+5x=4-8

8x = -4

x = -1/2 = - 0.5

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

8x +4 = 3x-1

8x -3x=-1-4

5x = -5

=> x = -1

6) 3x-10=5x-50

3x-5x=50+10

-2x=60

x=-30
