Answer:

  • (5, 2)

Step-by-step explanation:

<u>Given system:</u>

  • x + 2y = 9
  • x = 2y + 1

<u>Solve for y by substitution:</u>

  • (2y + 1) + 2y = 9
  • 4y + 1 = 9
  • 4y = 8
  • y = 2

<u>Find the value of x:</u>

  • x = 2*2 + 1
  • x = 5

Answer: y = 2

Step-by-step explanation:

we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:

since x=2y+1,

we can say that:

(2y+1)+2y=9

then we solve this equation,

first we expand the brackets- 2y+1+2y=9,

then we combine like terms- 4y+1=9

then we take 1 away from both sides- 4y=8

then we divided both sides by 4

y=2

Hope this helps xx
