Solve for x -1+2x+11=3x+3

$- 1 + 2 x + 11 = 3 x + 3$

Step 1

Add $- 1$ and $11$ .

$2 x + 10 = 3 x + 3$

Step 2

Move all terms containing $x$ to the left side of the equation.

Subtract $3 x$ from both sides of the equation.

$2 x + 10 - 3 x = 3$

Subtract $3 x$ from $2 x$ .

$- x + 10 = 3$

Step 3

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

Subtract $10$ from both sides of the equation.

$- x = 3 - 10$

Subtract $10$ from $3$ .

$- x = - 7$

Step 4

Divide each term in $- x = - 7$ by $- 1$ and simplify.

Divide each term in $- x = - 7$ by $- 1$ .

$\frac{- x}{- 1} = \frac{- 7}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{x}{1} = \frac{- 7}{- 1}$

Divide $x$ by $1$ .

$x = \frac{- 7}{- 1}$

Simplify the right side.

Divide $- 7$ by $- 1$ .

$x = 7$
