How do you solve the system of equations 4 x − 2 y = 1 and -4 + 4 y = -2

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.

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)
