Question

2x +-3y = 7 and 2x+3y=7 the x = ? y=​

Answer 1

Answer:

x=7/2 ; y=0, tell if you want detailed solution

Answer 2

To solve for a system of equations by graphing. Solve for two points we each equation, plot the points, draw a line through the points, determine where the two lines intersect:

Equation 1: 2x+3y=7

First Point: For x=2

(2⋅2)+3y=7

4+3y=7

4−4+3y=7−4

0+3y=3

3y=3

3y3=33

y=1 or (2,1)

Second Point: For y=3

2x+(3×3)=7

2x+9=7

2x+9−9=7−9

2x+0=−2

2x2=−22

x=−1 or (−1,3)

Equation 2: 2x−3y=13
