First let's distribute the minus sign.

$\twoheadrightarrow\sf 4x+7-x-6=68$

$\bullet$ Add 6 to both sides

$\twoheadrightarrow\sf 4x+7-x=74$

$\bullet$ Subtract the x's

$\twoheadrightarrow\sf 3x+7=74$

$\bullet$ Subtract 7 from both sides

$\twoheadrightarrow\sf3x=67$

$\bullet$ Divide both sides by 3

$\twoheadrightarrow\sf x=\cfrac{67}{3}$

$\bullet$ Great job! We solved for the variable

Answer 2

$4x + 7 - (x + 6) = 68 \\ \\ 4x + 7 - x - 6 = 68 \\ \\ 3x + 1 = 68 \\ \\ 3x = 68 - 1 \\ \\ 3x = 67 \\ \\ x = \frac{67}{3} \\ \\ x = 22.3$

The value of x is 67/3 or 22.3 .
