b) 2x - 10 + 7x + 10 = 180

Q: b) 2x - 10 + 7x + 10 = 180

To solve the equation $2x - 10 + 7x + 10 = 180$, follow these steps: 1. Combine like terms: \[ 2x + 7x - 10 + 10 = 180 \] \[ 9x = 180 \] 2. Solve for $x$ by dividing both sides by 9: \[ x = \frac{180}{9} \] \[ x = 20 \] So, the solution is $x = 20$.

Accepted Answer

To solve the equation $2x - 10 + 7x + 10 = 180$, follow these steps:

1. Combine like terms:
   $$
   2x + 7x - 10 + 10 = 180
   $$
   $$
   9x = 180
   $$

2. Solve for $x$ by dividing both sides by 9:
   $$
   x = \frac{180}{9}
   $$
   $$
   x = 20
   $$

So, the solution is $x = 20$.
