The first step for solving this expression is to move the constant to the right side of the equation and then change its sign. -9w = -29 - 7 Calculate the difference on the right side of the equation by extracting the negative sign. -(29 + 7) Now add the numbers together,, add the negative sign and put it back into the original equation. -9w = -36 Divide both sides of the equation by -9. -9w ÷ (-9) = -36 ÷ (-9) Remember that any expression divided by itself equals 1,, so the expression becomes the following: w = -36 ÷ (-9) Since dividing two negatives equals a positive,, the expression changes to: w = 36 ÷ 9 Lastly,, divide the numbers to get your final answer. w = 4 Let me know if you have any further questions. :)
