Given the statement:
x - 7 divide by 3 = 4x divide by 5
This can be represented as,
(x - 7)/3 =4x /5
Solution:
In order to solve for x, the first step is to cross multiply the two fractions.
(x - 7)/3 =4x /5
5(x - 7) = 4x (3)
5x - 35 = 12x
Transpose 5x on the other side of the equation, note that when transposing a number, the sign changes.
-35 = 12x - 5
-35 =7x
Divide both sides by 7 in order to get the value of x.
x = -5
Final answer:
x = -5
