3x + 2y = 12
2x - 3y = 21

Question:

A. Write the equations in slope-intercept form. (show your work)
B. Graph the equations.
C. Estimate the solution to the pair of equations.
can u plz hurry

Respuesta :

3x+2y=12
2y=-3x+12
y=-3/2x+6

2x-3y=21
-3y=-2x+21
Y=2/3x-7

To fond the solution make the equations equal to eachother and solve for x
-3/2x+6=2/3x-7
-3/2x-2/3x=-7-6
-13/6x=-13
x=6
Sub x into one of the equations to find y
Y=-3/2*6+6
Y=-9+6
Y=-3
Therefore the solution is (6,-3)
The graphs are above.
Hope this helps.
