Answer: D
Step-by-step explanation:
Answer:
2(Jill) - 20 + (Jill) = 205
3(Jill) = 225
(Jill) = 75
(Jack) = 2(75) - 20 => 150 - 20 = 130
Jill= 75
Jack= 130
Step-by-step explanation:
Answer:
B. 1,4
Step-by-step explanation:
1. substitute 4x for y in the second equation since we know y=4x(to find x)
6x-4(4x)=-10
2.solve for x
6x-4(4x)=-10
-4•4x=-16x
6x-16x=-10
6x-16x=-10x
-10x=-10
-10x/-10=-10/-10
x=1
3.substitute 1 for x in either equation(since x=1)to find y
y=4(1)
y=4
x,y=1,4
