Question

Solve the system 2x + 3y = 3 and 3x – 2y = 11 by using graph paper or graphing technology. What is the solution to the system?

(–3, 3)

(–1, –7)

(1, –4)

(3, –1)

Answer 1

Which are you using, paper or calculator?

Answer 2

paper..

Answer 3

Ok, then:
1) solve both systems for y in terms of x (put x's on one side, y's on the other; divide by the coefficient of y
2) Plot both lines
3) The solution is the point at which the two lines intersect

Answer 4

If you need elaboration on any step, just let me know.

Answer 5

2*(2x+3y)+3*(3x-2y)=6+33
13x=39
x=3
thus y=-1

Answer 6

@chanh_chung That is neither using a graph, nor using a graphing technology. Please read questions before responding.
