Answer: x = 8
Explanation:
The two lines are of the same length. We can write the equation 11 + 7x = 67 to represent this. We can simplify (solve) this equation by isolating our variable.
11 + 7x = 67 becomes:
7x = 56
We've subtracted 11 from both sides.
We can then isolate x again. By dividing both sides by 7, we get:
x = 8.
Therefore, x = 8.
