Solve 3x+3(x+1)=(4-x)*3

$$3 x + 3 ( x + 1 ) = ( 4 - x ) \cdot 3$$

Solve for x

$$x=1$$

Steps for Solving Linear Equation

Use the distributive property to multiply 3 by x+1.

$$3x+3x+3=\left(4-x\right)\times 3$$

Combine 3x and 3x to get 6x.

$$6x+3=\left(4-x\right)\times 3$$

Use the distributive property to multiply 4-x by 3.

$$6x+3=12-3x$$

Add 3x to both sides.

$$6x+3+3x=12$$

Combine 6x and 3x to get 9x.

$$9x+3=12$$

Subtract 3 from both sides.

$$9x=12-3$$

Subtract 3 from 12 to get 9.

$$9x=9$$

Divide both sides by 9.

$$x=\frac{9}{9}$$

Divide 9 by 9 to get 1.

$$x=1$$
