Answer:
(x - 5) and (x + 4)
Step-by-step explanation:
Since -20 = (-4)(5) or (4)(-5), and since -5x + 4x becomes -1x, we know right away that the factors are (x - 5) and (x + 4).
Answer:
31.5
and
32,4
Step-by-step explanation:
Infinitely amounts of solutions because -3y and 3y cancel each other out which means no matter what y is the outcome will always be 4.
The value of x and y in the given equation is determined -1 and -2 respectively.
<h3>
Value of x and y</h3>
The value of x and y can be determined by solving the two equations simultaneously.
y = -2x - 4 ----- (1)
y = 4x + 2 ----- (2)
solve (1) and (2) together
-2x - 4 = 4x + 2
-6x = 6
x = -1
y = 4(-1) + 2
y = -4 + 2
y = -2
