Question

solve for x.
10x - 3x + 5 = 26
options:
\frac{13}{6}
3
\frac{31}{7}
13

Explanation:

Step1: Combine like terms

$10x - 3x = 7x$, so the equation becomes:
$7x + 5 = 26$

Step2: Isolate the term with x

Subtract 5 from both sides:
$7x + 5 - 5 = 26 - 5$
$7x = 21$

Step3: Solve for x

Divide both sides by 7:
$x = \frac{21}{7} = 3$
