@TrixieDiVine question plz

For each of those answer choices, you can turn 2 equations into one equation using substitution. One of the answer choices will give you x + 4 = 3x + 12 right away withouth any work once you make the substitution.

I'm still really confused

OpenStudy (anonymous):

Example if I know that these 2 equations are true: y = 4x and y = 3x - 7 substitute 4x for y in the second equation and I get 4x = 3x - 7 Same idea for your problem here

hartnn (hartnn):

x+4 = 3x+12 put left side of equation as y= ... and right side also as y=.... what you get is a system of equation

OpenStudy (anonymous):

Look care fully ! We have the systems they have equations and in the all of the equations we have y means the equations are equal for example if we have : 9=3+8x 9=2-12x we have : 3+8x=2-12x so another example : y=9x+3 y=10x-2 9x+3=10x-2 Got it ?:)
