Answer 1

0=0

Step-by-step explanation:

4(×+3)=4x+12

4x+12=4x+12

Subtract 12 from both sides of the equation

4x+12-12=4x+12-12

simplify

4x=4x

Subtract 4x from both sides of the equation

4x-4x= 4x-4x

Simplify and combine like terms

0=0

Answer 2

Answer:

You can use any real number for x and make the equation true.

Step-by-step explanation:

A system of linear equations occurs when there are (usually) two equations of a line in which same solutions are sought.

A system of linear equations can be in three states: it can have one solution, it can have no solution, or it can have infinite solutions.

A SoLE (system of linear equations) with one solution is probably the most famous one. This means that the lines share an (x,y) coordinate point. When a system of equations with one solution is graphed, they cross at the point.

A SoLE with no solution means that the lines do not share an (x,y) coordinate. When graphed, they do not touch, ever. They can also be considered parallel to one another.

A SoLE with infinite solutions means that the lines always cross at every (x,y) coordinate they emcompass. When graphed, they are literally the same line.

In this case of 4(x+3) = 4x + 12, they are a SoLE with infinite solutions. This is because if I use the distributive property on 4(x+3), the equation then becomes:

4x + 12 = 4x + 12

They are the same thing.

So, if I input an x value, both sides of the equation will always equal each other.

For example, say that I subsitute 0 for x:

4(0 + 3) = 4(0) + 12

4(3) = 12

12 = 12

They equal each other as expected.

Let's take a weirder number to solidify my point, the constant e:

4(e + 3) = 4e + 12

4e + 12 = 4e + 12

Let's even take 1,000,000 as an example:

4(1,000,000 + 3) = 4(1,000,000) + 12

4(1,000,003) = 4,000,000 + 12

4,000,012 = 4,000,012

So yes, this goes to show how religious these SoLE with infinite solutions can be.
