Full solution

Q. rac{X+66}{77}=−2-2
  1. Isolate X by multiplying: Step 11: Isolate X by multiplying both sides by 77 to eliminate the denominator.\newline(X+6)/7=−2(X + 6)/7 = -2\newline⇒X+6=−2×7\Rightarrow X + 6 = -2 \times 7\newline⇒X+6=−14\Rightarrow X + 6 = -14
  2. Solve for X: Step 22: Solve for X by subtracting 66 from both sides.\newlineX+6−6=−14−6X + 6 - 6 = -14 - 6\newline⇒X=−20\Rightarrow X = -20
