Question

9 - 4(2x - 1) = 45 please help​

Answer 1

`x=-4`

Explanation:

`9-4(2x-1)=45`

First, we expand the equation using the distributive rule:

`x(y-z)=xy-xz`

Hence,
`9-4*2x-4*-1=45`

Simplify:
`9-8x+4=45`

Add like terms:

`13-8x=45`

Subtract 13 from both sides:
`-8x=32`

Divide both sides by -8:

`x=-4`
