Question

Solve for x: 3x + 2x + 7 = 10x - 16 What’s the answer ?

Answer 1

Answer:

$x=\frac{23}{6}$ or $4.6$

Step-by-step explanation:

$3x + 2x + 7 = 10x - 16$

$5x+7=10x-16$

Subtract 7 from both sides:

$5x+7-7=10x-16-7\\5x=10x-23$

Subtract 10x from both sides:

$5x-10x=10x-23-10x\\-5x=-23$

Divide both sides by -5:

$\frac{-5x}{-5}=\frac{-23}{-5}\\x=\frac{23}{5}$ or $4.6$
