What you help with exactly?
3/4x-12-5=15
3/4x-17=15
3x-68=60
3x=60+68
3x=128
X=128/3
Answer:
(2x-4)-(6-8x)
2x-4-6+8x
2x-10+8x
10x-10
Step-by-step explanation:
The question's asking the difference between 2 binomial polynomials.
1. To subtract them, you must use the distributive property to distribute the minus sign on the terms in the second polynomial.
2. Combine like terms. -4-6=-10, 2x+8x=10
<u>Answer is 10x-10</u>
Answer:
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
X+2y=10
-4x-y=2
first, isolate x in first equation: x=10-2y
substitute value of x in first equation (10-2y) into second equation:
-4(10-2y)-y=2
-40+8y-y=2
7y=42
y=6
put value of y (6) into either equation to solve for x
x+2(6}=10
x+12=10
x=-2
x=-2, y=6
prove by inserting x and y values into either equation
-4x-y=2
-4(-2)-6=2
8-6=2
2=2
or
x+2y=10
-2+2(6)=10
-2+12=10
10=10
