Answer:
y=2 x=5
Step-by-step explanation:
3x-2y=11
2x-3y=4
you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3
6x-4y=22
+ -6x-9y=12
--------------------------
0x+5y=10
y=2
you plug that in either equation
3x-2(2)=11
3x-4=11
3x=15
x=5

Step-by-step explanation:
Answer:
3x² - 6
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 2x² + 1 + x² - 7 ← collect like terms
= 3x² - 6
