Question

6x-10+3x=35 Solve for x

Answer 1

x = 5

Explanation:$6x\text{ - 10 + 3x = 35}$

collect like terms for x:

$\begin{gathered} 6x\text{ + 3x - 10 = 35} \\ 9x\text{ - 10 = 35} \end{gathered}$

subtract 10 from both sides:

$\begin{gathered} 9x\text{ - 10 + 10 = 35 + 10} \\ 9x\text{ + 0 =45} \\ 9x\text{ = 45} \end{gathered}$

divide both sides by 9:

$\begin{gathered} \frac{9x}{9}=\frac{45}{9} \\ x\text{ = 5} \end{gathered}$
