Answer:
x = -2
Step-by-step explanation:
3x+7=-x-1
4x+7=-1
4x=-8
x=-2
Answer: E
Step-by-step explanation:
To cancel out the Y you need to have both multiplied by each other
so the first equation get multiplied by 7 and the second one by 4
28y + -28y = 0 they cancel out
Angie buys 1 software package and 3 months of game play
Kenny buys 1 software package and 4 months of game play
price of each software package = $20
total cost = $117
cost of one month game play = ?
let y is the cost of one month play
Angie buys 3 months game play and paid $20 = 20 + 3y
Kenny buys 4 months game play and paid $20 = 20 + 4y
total cost of both is $117
So the equation becomes,
(20 + 3y) + (20 + 4y) = 117
7y + 40 = 117
7y = 117 - 40
7y = 77
dividing with 7 on both sides, we get
y = 11
so, $11 is the cost of one month game play
Answer:
33
Step-by-step explanation:
6z - 18 = 180
6z = 198
z = 33
E and in end up canceling each other out so say e was 2 you are adding -2 so the Anwser is f(x)= -13
