X = -4y+3
-x-4y = -3
________________
x+4y = 3
-x-4y = -3
0 = 0
Possible and determined system (single solution)
multiply both sides by .4 to isolate the x variable.
x = 1.6
Answer:
u= -3
Step-by-step explanation:Solve for
u by simplifying both sides of the equation, then isolating the variable.
I=prt
i=2000 X .04 X 7
i = 560
So you earned 560 after 7 years, plus your 2000 you started with
You can get C
Let A represent the amount Ann contributed, Z represent Zoe's contribution, and J represent Jim's contribution toward the present.
Ann (A): A
Zoe (Z): A = Z - 12 → Z = 12 + A
Jim (J): A = J - 16 → J = 16 + A
A + Z + J = 154
(A) + (12 + A) + (16 + A) = 154
3A + 28 = 154
3A = 126
A = 42
Ann (A): A = 42
Zoe (Z): Z = 12 + A = 12 + 42 = 54
Jim (J): J = 16 + A = 16 + 42 = 58
Answer: Ann=42, Zoe=54, Jim=58
