Multiply -2 by each term inside the parenthesis (x+3).
Complete the multiplication of -2 by each term inside the parenthesis.
Remove the parenthesis around the expression -2x-6.
Since -2x contains the variable to solve for, move it to the left-hand side of the equation by adding 2x to both sides.
Since -4x and 2x are like terms, subtract 2x from -4x to get -2x.
Since -7 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 7 to both sides.
Subtract 6 from 7 to get 1.
Divide each term in the equation by -2.
Simplify the left-hand side of the equation by canceling the common terms.
Simplify the right-hand side of the equation by simplifying each term.
therefore x = -1/2
