7 x 8 + 4 2 x 3 = 4 x 3
Multiply by the equation by 8 to get rid of the first fraction:
7 x + 32 16 x 3 = 32 x 24
Similarly multiply by 3 to get rid of the second fraction:
21 x + 96 16 x = 96 x 72
Now you can re-arrange and solve for x.
Collect like terms on both sides:
( 21 x 16 x ) + 96 = 96 x 72
( 5 x ) + 96 = 96 x 72
Get all terms with x on the left side and all other terms on the right side
5 x 96 x = 96 72
Simplify:
91 x = 168
NOTE:
I did the multiplication in 2 steps to show you "baby steps" but you could do it in a single step by finding the Lowest Common Multiple (LCM) of 8 and 3. which gives you 24.
