Answer:
Y=7+3x, x=-3, y=-2
Step-by-step explanation:
3x-5y=1. Equation 1
3x-y=-7. Equation 2
-y=-7-3x isolate for y in equation 2
y=7+3x multiplied by -1 to get positive y
3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1
3x-35-15x=1
-12x=36
x=-3
solve for y.
3x-5y=1
3(-3)-5y=1
-9-5y=1
-5y=10
y=-2
Sorry, i dont know that one. i wish i could help ya
12/6 = 2 10/0.0001 = 1000002*100000 = 200000When doing these problems try and see the numbers not as the whole number but in standard form, if you want to understand further ask a maths professor about standard form
