x + 2 3 + 8 2 5 × 1 + 5 = 6 \dfrac{x+2}{3} + \dfrac{8}{2} - 5 \times 1 + 5 = 6

x + 2 3 + 4 5 + 5 = 6 \dfrac{x+2}{3} + 4 - 5 + 5 = 6

x + 2 3 + 4 = 6 \dfrac{x+2}{3} + 4 = 6

x + 2 3 = 2 \dfrac{x+2}{3} = 2

x + 2 = 6 x + 2 = 6

x = 4 \boxed {x = 4}

Flip the entire equation around to help you answer the question:

( 6 - 5 ) / 1 + 5 + ( 8/2 ) - 3(2) = x x

Solve arithmetic in brackets:

1 / 1 + 5 + 4 - 6 = x x

Now you can solve the equation easily:

( 1 / 1 ) + ( 5 + 4 ) - 6 = x x

( 1 ) + ( 9 ) - 6 = x x

10 - 6 = x x

x x = 4.
