Question

4×+5×=18 sole the equation and verify your result

Answer 1

4x+5x=18
9x=18
x=18/9
x=2

verification:
4x + 5x=18
putting x value as 2
4×2+5×2=18
8+10=18
18=18
thus,
L.H.S = R.H.S

Answer 2

Hi

4x + 5x = 18 ---( 1 )

9x = 18

x = 18/9

x = 2

Verification :

Substitute x = 2 in equation ( 1 ) ,

we get

4 × 2 + 5 × 2 = 18

8 + 10 = 18

18 = 18 ( true )

Therefore ,

x = 2 is the solution.

I hope this helps you.
