-x+3y=1
4x+5y=13
first I'll solve for y
-x+3y=1
3y=x+1
y=x/3+1/3-->plug this in for y into the other equation
4x+5(x/3+1/3)=13
4x+5x/3+5/3=13
17x/3=34/3
17x=34
x=2--->plug this in for x in either equation and solve for y
-x+3y=1
-2+3y=1
3y=3
y=1, x=2
x = 3 and y = 2
2x-3y=13
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
y= -9
70000000y=35t
2x plus 3y
x = 3 and y = 2
2x-3y=13
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
(10,13)
y= -9
y=4
2x+3y=13 3x-y=3 x=2
(x, y) = (3, 7) is a solution.
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
70000000y=35t
