Answer and Step-by-step explanation:
Since we know that lines l and m are parallel (we are just proving that they are parallel), we can see that the two angles given are corresponding angles, so they are congruent to each other.
123 = 2x + 7
Subtract 7 from both sides.
116 = 2x
Now, divide both sides by 2.
58 = x
So, the value of x is 58.
