your LCD is 6x , so multiply each term by that
20 + 8x = 3(7+x)
20+8x = 21+3x
5x = 1
x = 1/5
Solve?
(10 / 3x) + (4/3) = (7 + x) / (2x)

If (10 / 3x) + (4/3) = (7 + x) / (2x) mean
10 / ( 3 x ) + 4 / 3 = ( 7 + x ) / ( 2 x ) then Multiply both sides by x
10 * x / ( 3 x ) + 4 * x / 3 = x * ( 7 + x ) / ( 2 x )
10 / 3 + 4 x / 3 = ( 7 + x ) / 2 Multiply both sides by 6
10 * 6 / 3 + 6 * 4 x / 3 = 6 *( 7 + x ) / 2
10 * 2 + 2 * 4 x = 3 * ( 7 + x )
20 + 8 x = 21 + 3 x Subtract 3 x to both sides
20 + 8 x - 3 x = 21 + 3 x - 3 x
20 + 5 x = 21 Subtact 20 to both sides
20 + 5 x - 20 = 21 - 20
5 x = 1 Divide both sides by 5
x = 1 / 5
10 / ( 3 x ) + 4 / 3 = ( 7 + x ) / ( 2 x ) then Multiply both sides by x
10 * x / ( 3 x ) + 4 * x / 3 = x * ( 7 + x ) / ( 2 x )
10 / 3 + 4 x / 3 = ( 7 + x ) / 2 Multiply both sides by 6
10 * 6 / 3 + 6 * 4 x / 3 = 6 *( 7 + x ) / 2
10 * 2 + 2 * 4 x = 3 * ( 7 + x )
20 + 8 x = 21 + 3 x Subtract 3 x to both sides
20 + 8 x - 3 x = 21 + 3 x - 3 x
20 + 5 x = 21 Subtact 20 to both sides
20 + 5 x - 20 = 21 - 20
5 x = 1 Divide both sides by 5
x = 1 / 5
