Answer:
sorry I don't know the answer
Multiply the top equation by 2 and combine both equations to leave x alone. It is better if you do this vertically but it is hard here.
(6x-2y=20)+(4x+2y=40)
10x=60
x=6
Plug x back in to one of the equations.
3(6)-y=10
18-y=10
-y=-8
y=8
Your solution is (6,8)
Answer:
y = 55x + 15
Step-by-step explanation:
i think this is it, but it might not be right
Answer:
I think its 55.5
Step-by-step explanation
Sorry if I got it wrong for you
X = jane, y = jasmine, z = jocelyn
x + y + z = 56
x = 3z
y = 2z + 2
3z + 2z + 2 + z = 56
6z + 2 = 56
6z = 56 - 2
6z = 54
z = 54/6
z = 9 <==== jocelyn
x = 3z
x = 3(9)
x = 27 <=== jane
y = 2z + 2
y = 2(9) + 2
y = 18 + 2
y = 20 <=== jasmine
