Answer : x = 3

3x+8=5x+2 where X is 3

Explanation :-

Given :-

3x+8=5x+2,Solve the given equation without transposing and check your result.

3x+8=5x+2

Subtract 5x on both sides

3x - 5x +8 = 5x - 5x +2

-2x + 8 = 2

Subtract 8 on both sides

-2x +8 -8 = 2 - 8

-2x = - 6

Divide - 2 on both sides

-2x/-2 = -6/-2

x = 3.

Checking results :-

3x+8=5x+2

Substitute the value of x

3(3) +8 = 5(3) +2

9 + 8 = 15 + 2

17 = 17.

LHS = RHS

hence, verified
