Question

How do you solve `7p - ( 3 p + 4 ) = - 2 ( 2 p - 1 ) + 1 0`?

Answer 1

`color(green)(p=2)`

Explanation:

`7p-(3p+4)`
`color(white)("XXX")=7p-3p-4`
`color(white)("XXX")=4p-4`

`-2(2p-1)+10`
`color(white)("XXX")=-4p+2+10`
`color(white)("XXX")=-4p+12`

`:. 7p-(3p+4)=-2(2p-1)+10`
`rarr 4p-4 =-4p+12`

`rarr 8p=16`

`rarr p=2`
