Explanation

Let's solve the equation:

4/5 (x + 7) = 3(2x - 7)

Multiply both sides by 5 to eliminate the fraction:

4(x + 7) = 15(2x - 7)

Expand both sides:

4x + 28 = 30x - 105

Subtract 4x from both sides:

28 = 26x - 105

Add 105 to both sides:

133 = 26x

Divide both sides by 26:

x = 133/26
