Question

solve the equation and check your solution by substituting in the equation 3x-9=5x-3

Answer 1

3x-9=5x-3
3x-5x=-3+9
-2x=6
x=-3
putting the value of x in equation
3×(-3)-9=5(-3)-3
-18=-18
LHS=RHS

Answer 2

✍✍HERE IS YOUR ANSWER...⬇⬇
====================================

$\underline{SOLUTION}$ ➡

$3x - 9 = 5x - 3 \\ \\ = > 3x - 5x = - 3 + 9 \\ \\ = > - 2x = 6 \\ \\ = > x = \frac{6}{ - 2} \\ \\ = > x = - 3$

$\underline{CHECKING}$ ➡

$\boxed{x = -3} \\ \\ Putting \: \: the \: \: value \: \: of \: x \: \: in \: \: the \: equation :- \\ \\ We \: \: get,$

$3x - 9 = 5x - 3 \\ \\ = > 3 \times ( - 3) - 9= 5 \times ( - 3) - 3 \\ \\ = > - 9 - 9 = - 15 - 3 \\ \\ = > - 18 = - 1 8 \\ \\ So , \\ \\ L.H.S. = R H.S.$
