Answer:

  • $9 and $7

Step-by-step explanation:

<u>The first equation:</u>

  • x + 2y = 23

<u>The second equation:</u>

  • 2x + 3y = 39

<u>Convert to slope-intercept form:</u>

  • x + 2y = 23 ⇒ 2y = -x + 23 ⇒ y = -1/2x + 11.5
  • 2x + 3y = 39 ⇒ 3y = -2x + 39 ⇒ y = -2/3x + 13

<em>The graph is attached</em>

<u>Intersection point is (9, 7)</u>

masya89 [10]

Answer:

D

Step-by-step explanation:

Either try all the numbers and see which ones work or do the following.

Times both sides by 2x-5.

3=x(2x-5)=2x^2-5x

Rearrange and solve the quadratic. I will factorise.

2x^2-5x-3=0

(2x+1)(x-3)=0

so x = -1/2 or 3
