Question

solve the following equation by trial-and-error method
5x = 2x + 9
answer it correctly please​

Answer 1

Answer:

Step-by-step explanation:

5x = 2x+9

subtract 9 from both sides

we get 5x-9 = 2x+9-9

5x-9 = 2x

now subtract 2x from both sides we get

5x-2x-9=2x-2x

so 3x-9 = 0

now add 9 on both sides we get

3x-9+9 = 9

3x=9

divide by 3 on both sides

x = 3

Answer 2

Step-by-step explanation:

5x = 2x + 9

ans :-putting 1 at x

5 (1) = 2×1 + 9

5 = 2 +9

5≠9

putting 2

5(2) = 2 × 2 + 9

10 ≠ 13

putting 3

5 (3) = 2(3) + 9

15 = 6+9

15 = 15

hence solve , by trial and error method..Mark as brainlist
