Step-by-step explanation:
5x+2y=-11
2x+2y=5
so you find values that match or can multiply by something to match-2
5x+2y=-11
- 2x+2y=5
=3x+0y=-16
3x/3=-16/3
x=5 1/3
then substitute x in one of the equations to get y
The sum of two numbers
6x6=36
Twice first number
6x2=12
Minus the second
12-6=6
ANSWER
First number=6 Second number=6
Answer:
42
Step-by-step explanation:
g(-5)=-5.-5+17
=25+17
=42
3a^5 - (-a^5) = 3a^5 + a^5 = 4a^5
6a^7 - 2a^7 = 4a^7
-3a^5 - (-2a^5) = -3a^5 + 2a^5 = -a^5
7a^7 - 8a^7 = -a^7
