5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
Answer:
option D is correct answer
Answer:
A) Subtract 5 from each side
Step-by-step explanation:
This would be your first step, then you would want to isolate your variable so you would divide both sides by 2.
Answer:
2x+y=
1 beacuse ...... i had the same question
Step-by-step explanation:
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.
3x/5+25y=10, multiply all terms by 5 and the denominator cancels out
3x+125y=50, subtract 3x from each side
125y=-3x+50, divide both sides by 125
y=(-3+50)/125
slope=m=-3/125
y intercept=b=2/5
