Sandra did not get enough points.
They needed 15, but got 22 and a -8 as well.
So 22-8 = 14
14<15
2x+8+6=22
2x+14-14=22-14
2x = 8
2x/2 = 8/2
x = 4
Check your work
2(4+4)+6=22
2(8)+6=22
16+6=22
22=22
Answer:
infinitely many solutions
Step-by-step explanation:
Given the 2 equations
2x + 2y = 18 → (1)
x + y = 9 → (2)
Equation (1) is twice (2)
Thus the equations are equal and will have infinite solutions
