Answer:(-2,2)

Step-by-step explanation:

2x+3(1/2x+3)=2

⇒7/2x=-7

÷7⇒1/2x=-1

×2⇒x=-2

x=-2 into the equation

⇒2×(-2)+3y=2

⇒3y=6

⇒y=2

Answer:

(-2 , 2)

Step-by-step explanation:

2x + 3y = 2 ---------------(I)

y = (1/2)x + 3  --------------(II)

Substitute y value in equation (I)

[tex]2x + 3*[ \frac{1}{2}x + 3] = 2\\\\2x + 3*\frac{1}{2}x+3*3=2\\\\2x+ \frac{3}{2}x+9=2\\\\2x + \frac{3}{2}x = 2-9\\\\2x + \frac{3}{2}x = -7 \\[/tex]

Multiply the whole equation by 2

[tex]2*2x + 2* \frac{3}{2}x = -7 *2\\\\4x + 3x = -14[/tex]

        7x = -14

           x = -14/7

x = -2

Plugin x = -2 in equation (I)

2*(-2) + 3y= 2

-4 + 3y = 2

Add 4 to both sides

3y = 2+4

3y = 6

Divide both sides by 3

y = 6/3

y = 2
