how do i do this problem 0.25(x+4)-3=28

Distribute the .25 to get .25x + 1 - 3 = 28

Then simplify to get .25x - 2 = 28

Move the two to the right to get .25x = 30

Then divide to leave x: 30 / .25 = 120

X = 120

Answer:

[tex]x = 120[/tex]

Step-by-step explanation:

We can break this down into a handful of steps.

[tex]0.25(x+4)-3=28[/tex]

Firstly, you can simplify right off the bat via distribution.

[tex](0.25)(x)+(0.25)(4)+-3=28[/tex]

[tex]0.25x+1+-3=28[/tex]

Then, combine like terms.

[tex](0.25x)+(1+-3)=28[/tex]

[tex]0.25x+-2=28[/tex]

[tex]0.25x-2=28[/tex]

By using the additive property of equality, add 2 to both sides of the equation.

[tex]0.25x-2+2=28+2[/tex]

[tex]0.25x=30[/tex]

Then, divide both sides by 0.25.

[tex]\frac{0.25x}{0.25}[/tex] = [tex]\frac{30}{0.25}[/tex]

[tex]x=120[/tex]
