2 answers:
Answer:
x=1
y=-1
Step-by-step explanation:
x = y+2
x+2y = 5
y+2 +2y = 5
3y +2 = 5
3y = 3
y=1
x=-1
Answer:
Step-by-step explanation:
Insert y+2 into your x so...
y+2+2y=5
Then solve...
Combine like terms so 2y+y is 2y^2 (squared)
and..
5-2 is 3
you are left with 2y^2 (squared) = 3 is 0.75

(4x2 + 2y)(3x+y^2)
= 12x^3 + 4x^2y^2 + 6xy + 2y^3
coefficient of xy is ----> 6

Parentheses first:
So, 12 + 4 x 13 - 2
12 + 52 - 2
64 - 2
62
