Answer:
by factoring the answer is - x=1/2, 5
Step-by-step explanation:
hope it helps:))
The answer is 80, 2x+3x+4x=180, so x=20. 20*4=80.
Answer: y= -2 - 1/2
Step-by-step explanation:
-4x -2y = 1
+4x +4x
-2y = 4x + 1
/-2 /-2 /-2
y= -2 - 1/2
I think, i may be incorrect but the verbal explanation is; -4x is needed to be moved so you add 4x to both sides and 4x cancels out on the left which leaves -2y on the left (when it was moved "x" is always first). then divide all numbers by -2 to get y by itself. this gives you y= -2 - 1/2 if my calculations are correct.
B. 12/18
Upon simplifying this fraction (taking a 3 out of the numerator and denominator), you end with 4/6
