Answer:
x = 42
Step-by-step explanation:
Cross multiplying is done as follows:
<em>the </em><em>denominator </em><em>of the second </em><em>fraction </em><em>is </em><em>multiplied </em><em>with the </em><em>numerator </em><em>of the first </em><em>equation</em> and <u>denominator of the first fraction is multiplied with the numerator of the second equation</u>
5(3x+6) = 4(4x-3) multiply inside the parenthesis
15x + 30 = 16x - 12 transfer like terms to same side of the equation
30 + 12 = 16x - 15x
42 = x
