Answer:
x=5
y=2
Step-by-step explanation:
5x + 3y= 31
-6x - 3y = -36 (multiple by -3)
-x=-5
x=5
2(5)+y=12 or 25 + 3y= 31
10+y=12 3y=6
y=2 y=2
Answer:
5, 29 will both blank boxes
Step-by-step explanation:
the product of (4z^2 + 7z – 8) and (–z + 3)
(4z² + 7z – 8)(–z + 3)
-z(4z² + 7z – 8) + 3(4z² + 7z – 8)
-4z³-7z²+8z+12z²+21z-24
choose like terms
-4z³-7z²+12z²+8z+21z-24
-4z³+5z²+29z-24
5, 29
Answer:
False because on the left side of the equation you are adding 18 and 35 first and on the right you are multiplying 35 and 4 first. This will give you an unequal equation when solved.
Let's solve each side
(18+35)*4=212
but 18+(35*4)=158
