Modeling an Equation

Use the algebra tiles to model the equation
2x + 4 = 3x + (−1). Then complete the sentences.

To model 2x + 4, you need:


positive x-tiles to represent 2x.

positive unit tiles to represent 4.

To model 3x + (−1) you’ll need:

3
x-tiles to represent 3x.
1
unit tile to represent –1.

Sagot :

Yes all your used tiles are correct.

Let's solve the equation too

  • 2x+4=3x+(-1)
  • 2x+4=3x-1
  • 4+1=3x-2x
  • x=5

The value of variable x in the equation 2x+4=3x+(-1) is 5.

What is equation?

Equation is a relationship between two or more variables that are expressed in equal to form. Equation of twwo variable looks like ax+y=c. It cab be linear equation, quadratic equation and cubic equation. linear equation has a straight line curve.

How to solve equation?

We have been given equation 2x4=3x+(-1) and we have to solve the equation. Our equation has only one variable, so we have to solve for that variable only.

2x+4=3x+(-1)

2x+4=3x-1

5=x

Hence the value of x in the equation 2x+4=x+(-1) is 5.
