Answer:
x=1, x=8
Step-by-step explanation:
4x2−36x+32=0
Step 1: Factor left side of equation.
4(x−1)(x−8)=0
Step 2: Set factors equal to 0.
x−1=0 or x−8=0
(+1) (+8)
x=1 or x=8
Answer:
10 and 4.
Step-by-step explanation:
Let x be the first number.
Let y be the second number.
x + y = 2x - 6
x - y = 4y - 10
x = 4y - 10 + y
x = 5y - 10
(5y - 10) + y = 2(5y - 10) - 6
6y - 10 = 10y - 20 - 6
6y - 10 = 10y - 26
6y - 10y = -26 + 10
-4y = -16
y = 4
x - (4) = 4(4) - 10
x - 4 = 16 - 10
x - 4 = 6
x = 6 + 4
x = 10
