Answer:
x = 3
Step-by-step explanation:
Multiply the first equation by -1, then add it to second equation.
2x+9y = -12
-2x-7y = 8
-------------------
2y = -4
Solve for y
2y = -4
y = -2
Plug value of y into one of the equations and solve for x
2x + 9(-2) = -12
2x = 6
x = 3
Think of integers that have a sum (addition) of 8 that don't include negative integers.
4+4=8
6+2=8
5+3=8
Pat is right there are three different pairs of integers that can have a sum of 8.

Answer:
X=7
Step-by-step explanation:
2 + |x-4| = 5
2 + x -4 = 5
2 + x = 5 + 4
2 + x = 9
x = 9 - 2
x=7
