URGENT 15 POINTS!!!!What is the solution of the system?
ohaa [14]
The elimination method is a sufficient way to solve problems. 

2x+y= 20
6x-5y=12

Add 5y to the one equation.

2x+6y= 20
6x= 12

Subtract 2x from both sides. 

6y= 20
4x= 12

Divide 6 by 20. 
y= 3.3 

Divide 4 by 12.
x= 3

I hope this helped you!

Brainliest answer is appreciated!

Solve for substitution 8x+2y=13 and 4x+y=11
damaskus [11]
Solving for X:
1) y=-8x+6.5   y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5        (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5         (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125

Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5

y=-4(-1.125)+11
y=4.5+11
y=15.5

x=-1.125
y=15.5
or
(-1.125,15.5)
