I don't know how to solve this! Do I distribute the 15 and the negative sign? Please help! Thank you!
anastassius [24]
You would first subtract 2 and 15 from both sides so you'll get -(3x+5)= -9 and then the negative would go into the 3 and 5 so it would be -3x-5 = -9 and then you'll add 5 to both sides then divide -3 to both sides so you'll get
\frac{ - 4}{ - 3}
but since 2 negative make a positive your final answer is
\frac{4}{3}
