Answer 2

Question given:

$\frac{1}{3} (7x - 1) = \frac{1}{4}$

Answer:

$\frac{1(7x - 1)}{3} = \frac{1}{4}$

$\frac{7x - 1}{3} = \frac{1}{4}$

Cross Multiply:

$(7x - 1)(4) = 3(1)$

Distribute into the parentheses:

Hint:

$7x(4) - 1(4) = 3(1)$

$28x - 1(4) = 3(1)$

Hint:

$28x - 4 = 3(1)$

Hint:

$28x - 4 = 3$

Hint:

$28x - 4 = 3 \\ \: \: \: \: \: \: \: \: \: \: + 4 \: \: \: + 4$

$28x = 7$

Hint:

$\frac{28x}{28} = \frac{7}{28}$

$x = \frac{7}{28}$

Answer:

$x = \frac{1}{4}$
