Question

Please I need Help Im confused

Answer 1

x=3.5 y=8

Explanation:

Remeber, in a rectangle, opposite sides are equal so

`2x + 3y = 31`

and

a

`2x + 1 = y`

Subsitue 2x+1 for y.

`2x + 3(2x + 1) = 31`

`2x + 6x + 3 = 31`

`8x + 3 = 31`

`8x = 28`

`x = 3.5`

Plug this back in to one of the equations to find y.

`2x + 1 = y`

`2(3.5) + 1 = y`

`7 + 1 = y`

`8 = y`

So x=3.5

y=8
