Use substitution to solve the system
5x+4y=12
Y=2x-10
2 answers:
Ok so do you know the steps for substitution
Substitute the 2x-10 in for I in the first equation:
5x+4(2x-10) =12
Distribute the 4:
5x+8x-40=12
Add 40 to both sides and combine the x terms:
13x=52
Divide by 13:
x=4
Plug the 4 into either equation for the x value:
y=2(4)-10
y=8-10
y=-2
Answer:
X=4
Y=-2
To check you can plug them into either one of the equations.

Answer: q=7
Step-by-step explanation:
The answer to our question is yes
It would be H because 13 has no factors other than 1, and 13.
Hope this helps!
So because 25%=1/4 we would know to multiply 9*4
Which would get our answer to be 36 :)
