Solve for x.

5 (x - 3) + 4 (x + 3) = 3 (x - 1)

x = 0

x = 1/4

x = 1/2

x = 1

Simplify the left side.

5x-15 + (4x+12) = 3 (x-1)

Simplify by adding terms.

Remove unnecessary parentheses. 5x-15+4x+12=3 (x-1)

Add 5x and 4x to get 9x. 9x-15+12=3 (x-1)

Add - 15 and 12 to get - 3. 9x-3=3 (x-1)

Simplify the right side.

Apply the distributive property. 9x-3=3x+3⋅ - 1

Multiply 3 by - 1 to get - 3. 9x-3=3x-3

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

Since 3x contains the variable to solve for, move it to the left side of the equation by subtracting 3x from both sides. 9x-3-3x = - 3

Subtract 3x from 9x to get 6x. 6x-3=-3 Move all terms not containing x to the right side of the equation.

Since - 3 does not contain the variable to solve for, move it to the right side of the equation by adding 3 to both sides. 6x=3-3 Subtract 3 from 3 to get 0. 6x=0 Divide each term by 6 and simplify. x = 0
