Algebra STAAR Review (for studying)

What BY HAND method and DESMOS trick could you use to solve the problem below:

What is the value that makes 2(x-1) = 4(3x+2) true?

• BY HAND: Isolate x by distributing and moving the like terms

  DESMOS: Type in the left side of =, underneath type in the right, find the intersection

• BY HAND: Add all like terms

  DESMOS: Look for equivalent graphs

• BY HAND: Isolate x by combining like terms and distributing

  DESMOS: Type in a table and use y1 ~ mx1+b

• BY HAND: Just distribute

  DESMOS: Type in and look for the x-intercepts

Which of the following is NOT another work for an x-intercept?

• Vertex

• Solution

• Zero

• Root

What is the value that makes 2(x-1) = 4(3x+2) true?
