Question

X+2y=9 and x=2y+1

helppppppppppppppppp meeeeereeer​

Answer 1

Answer: y = 2

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

Answer 2

• (5, 2)

Explanation:

Given system:

• x + 2y = 9
• x = 2y + 1

Solve for y by substitution:

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

Find the value of x:

• x = 2*2 + 1
• x = 5
