For this one you want to cancel out the x-terms.
Multiply top equation by -2
---> -2x -10y = 6
---> 2x +7y = 3
Add them together
---> -3y = 9
Solve for y ...

$641.91
Step-by-step explanation:
A(t) = 570(1+0.02)^6
The solution of the equation x2+7x is 0, -7 using the quadratic formula.
Step-by-step explanation:
x2 + 7x = 0
-b ± √
b2 - 4(ac)/ 2a
substitution,
a = 1, b = 7, c = 0
= -7 ± √(7)2 - 4(1 x 0) / 2 x 1
= - 7
± 7 / 2
x = 0 , -7
