Question 3 of 5
Two Variables

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

Solve 4a + 2a = 8a - 5x + 8 for a in terms of x.

1\(\frac{3}{4}\)x - 2
-\(\frac{4}{5}\)x + 1\(\frac{1}{5}\)
\(\frac{2}{3}\)x - \(\frac{2}{3}\)
\(\frac{6}{7}\)x + \(\frac{1}{7}\)
