Answer:
One solution
Step-by-step explanation:
x+y=5
3x-y=-5
Add the equations together will get you:
4x=0
Divide the 0 by 4 to get the x alone will get you
x=0
Answer:
We know that lines <em>l</em><em> </em>and <em>m</em><em> </em>are parallel. The alternate interior angles rule states that the alternate interior angles formed by parallel lines are equal. So let's equate them.
2x + 22 = 4x
putting variables on one side,
22 = 4x - 2x
Thus 2x = 22
x becomes 22÷2
Therefore,<u> x = 11.</u>
