Answer:
x = 11 and y = 4
Step-by-step explanation:
Given equations are :
x+y=15 ...(1)
-2x+5y=-2 ...(2)
We need to solve the systems of equations.
Multiply equation (1) by 2.
2x+2y=30 ...(3)
Adding equation (2) and (3).
-2x+5y+2x+2y = -2+30
7y = 28
y = 4
Put the value of y in equation (1).
x+4=15
x = 11
So, the solution of the given equations are x = 11 and y = 4.
Answer:
I got you, give me a few minutes
1st one: 6x+12+6y
2nd one: -12a-20b
4th one: 2x times 18
Step-by-step explanation:
Answer:
i got negative 108
Step-by-step explanation:
i got this because just put it in a porportion like x/y = x/?
then plug in the numbers it gives you. so it should look like this 5/-45 = 12/?
then multiply 12 and -45 and then divide by 5. you should get -108
