Question

Transposition method 9x = (18 - x) +12
solve →​

Answer 1

Answer:

x = 3

Step-by-Step Explanation:

9x = (18 - x) + 12

9x = 18 - x + 12

9x + x = 18 + 12

10x = 30

x = 30 ÷ 10

x = 3

Verification:

LHS = 9x

= 9 × 3

= 27

RHS = (18 - x) + 12

= (18 - 3) + 12

= 15 + 12

= 27

LHS = RHS hence, verified.

Hope it helps

Answer 2

Answer:

X=10.50

Step-by-step explanation:

9X=18-X +12

X+X=18+12-9

2X=21

X=21/2

X=10.50
