Step 1 distribute the 6 and -5

18x+30-2x-5x+15=210

Step 2: combine like terms

18x-2x-5x+30+15=210

11x+45=210

Step 3: subtract 45 from both sides

11x+45-45=210-45

11x=165

Step 4: Divide by 11 on both sides

11x/11=165/11

X=15

Step 5: Check

6(3(15)+5)-2(15)-5(15-3)=210
6(50)-30-5(12)=210
300-30-60=210
300-90=210
210=210

Final Answer:

X=15
