Q:

Given: 18x-2(3x+1)=5x-16Prove: x=-2

Accepted Solution

A:
Answer:X = -2 Step-by-step explanation:(If you mean to "check the answer" then the answer above mine would help more)I hope this answer helps. You should show your work as proof:We simplify the equation first:18xβˆ’2(3x+1)=5xβˆ’1618x+(βˆ’2)(3x)+(βˆ’2)(1)=5x+βˆ’16 (Distribute)18x+βˆ’6x+βˆ’2=5x+βˆ’16(18x+βˆ’6x)+(βˆ’2)=5xβˆ’16 (Combine Like Terms)12x+βˆ’2=5xβˆ’1612xβˆ’2=5xβˆ’16Then we cancel out:12xβˆ’2βˆ’5x=5xβˆ’16βˆ’5x7xβˆ’2=βˆ’167xβˆ’2+2=βˆ’16+27x=βˆ’147x/7 = βˆ’14/7x = -2
