@TrixieDiVine question plz

Answer 4

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.

Answer 5

I'm still really confused

Answer 6

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

Answer 7

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

Answer 8

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 ?:)
