Answer
Explanation:
Step1: Combine like terms
The sum of (2x) and (9x - 6) is equal to (71^{\circ}). So, (2x+(9x - 6)=71). Using the distributive property (a+(b - c)=a + b - c), we get (2x+9x-6 = 71). Combining (2x) and (9x) (since (2x+9x=(2 + 9)x=11x)), the equation becomes (11x-6 = 71).
Step2: Solve for (x)
Add (6) to both sides of the equation (11x-6 = 71). We have (11x-6+6=71 + 6), which simplifies to (11x=77). Divide both sides by (11): (x=\frac{77}{11}).
