Solve for x 10-3x+8x=25

$10 - 3 x + 8 x = 25$

Step 1

Add $- 3 x$ and $8 x$ .

$10 + 5 x = 25$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Subtract $10$ from both sides of the equation.

$5 x = 25 - 10$

Subtract $10$ from $25$ .

$5 x = 15$

Step 3

Divide each term in $5 x = 15$ by $5$ and simplify.

Divide each term in $5 x = 15$ by $5$ .

$\frac{5 x}{5} = \frac{15}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 x}{5} = \frac{15}{5}$

Divide $x$ by $1$ .

$x = \frac{15}{5}$

Simplify the right side.

Divide $15$ by $5$ .

$x = 3$
