9 - 4(2x - 1) = 45 please help​
ddd [48]

Answer:

x=-4

Step-by-step 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
