Answer
$3\frac{2}{3}$
Work Step by Step
$7(3x - 4) = 49$
Using BODMAS, we start by opening up the brackets as below:
$21x - 28 = 49$
Next, we isolate the variable $x$ by adding $28$ to both sides as below:
$21x - 28 + 28 = 49+ 28$
Simplifying we have:
$21x = 77$
Divide through by the coefficient of $x$ as shown below:
$\frac{21}{21}x = \frac{77}{21}$
Simplify to get:
$x = \frac{11}{3}$
Leaving the answer to the simplest form we have:
$x = 3\frac{2}{3}$
