Similar Problem (same idea, the numbers are changed)


You want to isolate x. Here's how you do it:


x+3 = -5(2x+6) ... Start with the given equation.


x+3 = -10x-30 ... Distribute


x = -10x-30-3 ... Subtract 3 from both sides.


x+10x = -30-3 ... Add 10x to both sides.


11x = -33 ... Combine like terms.


x = -33/11 ... Divide both sides by 11 to fully isolate x.


x = -3 ... Divide


So the final answer is x = -3
