Question

1. Solve the following equation for x: 2x + 5y = 8.

A. x = 5 over 2y +4
B. x = -5 over 2y -4
C. x = 5 over 2y -4
D. x = -5 over 2y +4

Answer 1

D.
`x = (-5)/(2) + 4`

Explanation:

`2x + 5y = 8\\`

Subtract 5y from both sides

`2x = -5y +8`

Divide both sides by 2

`x = (-5)/(2) + 4`

Hope this helps!

Answer 2

The correct option is D)
`x=(-5y)/(2)+4`

Explanation:

Consider the provided equation.

`2x+5y=8`

We need to solve the provided equation for x.

Subtract 5y from both side.

`2x+5y-5y=8-5y`

`2x=8-5y`

Divide both sides by 2.

`(2x)/(2)=(8-5y)/(2)`

`x=(8-5y)/(2)`

`x=(-5y+8)/(2)`

`x=(-5y)/(2)+4`

Hence, the value of the equation is
`x=(-5y)/(2)+4`

Thus, the correct option is D)
`x=(-5y)/(2)+4`
