B) X+4y=7
It works with both equations
-6x + 2y = 8
isolate the y
first add 6x to both sides
2y = 6x + 8
then divide everything by 2 to isolate the y
y = 3x + 4
Hope this helps
I believe its going to be discrete
OK. Here we go:
Step #1: Write the equation on your paper.
Step #2: Add 3 to each side of the equation.
Step #3: With the result of step-#2, divide each side of the equation by 2.
If your result of step-#3 is not 4.5, then go back to step-#1, and go through
all 3 steps again, trying to be more careful and focused.
