Answer:

x=1

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

3x−2y=1;2x+2y=4

Step: Solve3x−2y=1for x:

3x−2y+2y=1+2y (Add 2y to both sides)

3x=2y+1

x 3 = 2y+1 3  (Divide both sides by 3)

x= 2 3 y+ 1 3

Step: Substitute  2 3 y+ 1 3 for xin 2x+2y=4:

2x+2y=4

2( 2 3 y+ 1 3 )+2y=4

10 3 y+ 23 =4 (Simplify both sides of the equation)

10 3 y+ 2 3 + −2 3 =4+ −2 3  (Add (-2)/3 to both sides)

10 3 y= 10 3

10 3 y 10 3 = 10 3 10 3  (Divide both sides by 10/3)

Step: Substitute 1 for yin x= 2 3 y+ 1 3 :

x= 2 3 y+1 3

x= 2 3 (1)+ 1 3

x=1 (Simplify both sides of the equation)

That was a lot to type.
