Question

Solve the equations:
(i) 4x + 8 = 9x - 7
(ii) 2/3 m = 8​

Answer 1

Answer:

x=3

m = 12

Step-by-step explanation:

4x + 8 = 9x - 7

Transpose LHS and RHS

8+7 = 9x - 4x

15 = 5x

x = 15 / 5

x = 3

2/3 m = 8​

m = 8 ÷ 2/3

m= 8 x 3/2(Reciprocal of 2/3)

m = 12

Answer 2

Step-by-step explanation:

i) 9x -4x= 8+7

or, 5x =15

or, X=15/5

X = 3

ii) 2/3m=8

or, 2m=24

or, m=24/2

m =12
