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:

$x=-4$

What are the solutions (coordinate points) to the system of equations?

Viefleur [7K]

Answer:

x=0,-2

Step-by-step explanation:

Solve the solution by equaling them to each other and solve for x.

x^2+5x+6=3x+6

x^2+5x-3x+6-6=0

x^2+2x=0 (factor out one x)

x(x+2)=0

x has two solutions since there are two options of solving.

1. x=0/(x+2)

x=0

2. x+2=0/x

x+2=0

x=-2
