Answer:
x=3, y=-2. (3, -2).
Step-by-step explanation:
4x+2y=8
5x+3y=9
---------------
simplify 4x+2y=8 into 2x+y=4
-----------------
2x+y=4
5x+3y=9
----------------
y=4-2x
5x+3(4-2x)=9
5x+12-6x=9
-x=9-12
-x=-3
x=3
2(3)+y=4
6+y=4
y=4-6
y=-2

Answer:
90 games
Step-by-step explanation:
Of the 120 games the football team played, they won 75% of them.
Remember that in mathematics, "of" almost always means to multiply. Here, that means we must multiply 75% by 120:
75% * 120
Remember also that % just means divided by 100, so 75% = 75 / 100. So:
75% * 120 = (75/100) * 120 = 9000/100 = 90 games
