Question

2/5d+4/9e=-2d+7/18e-1
solve for e

Answer 1

The answer is e = -5e—90
____ 216 hopes this help

Answer 2

`e=(-5e-90)/(216)`

Explanation:

`(2)/(5)d+(4)/(9)e=-2d+(7)/(18)e-1`

`(2)/(5)d+(4e)/(9)=-2d+(7)/(18)e-1 < - Muiltiply`

`(2)/(5)d+(4e)/(9)=-2d+(7e)/(18)- < - Muiltiply Again\\`

`(2)/(5)d+(4e)/(9)-(4e)/(9)=-2d+(7e)/(18)-1-(4e)/(9) < - Subtract BothSides`

`(2)/(5)d=-2d-(e)/(18)-1 < - Simplify`

`(2)/(5)d+2d=-2d-(e)/(18)-1+2d < - AddToBothSides`

`(12)/(5)d=-(e)/(18)-1 < - Simplify`
`(12d)/(12)=-((5e)/(18))/(12)-(5)/(12) < - DivideBothSides`

`e=(-5e-90)/(216)`
