2( 4x + 2) = 4x - 12(x-1)​
aksik [14]

Answer:

x=\frac{1}{2}

Step-by-step explanation:

distribute 2 into (4x+2) and -12 into (x-1)

8x+4=4x-12x+12

combine like terms

8x+4=-8x+12

add -8x on both sides

8x+8x+4=12

16x+4=12

subtract 4 on both sides

16x=8

divide both sides by 16

x=1/2

hope this helps

Determine which system below will produce infinitely many solutions.
mariarad [96]
A system that will produce infinitely many solutions will have the property where all the equations overlap. That means they will have the same slope and y-intercept.

An easy way to determine if they will produce infinitely many solutions is to put all the equations into y=mx+b form. If everything is the same, you know it will have infinite solutions.
