How do I solve this? I need step by step
y=2x
x=-y+6

Notice that y = 2x, which means you can replace any y and turn them into 2x

x = -y + 6

x = -(2x) + 6

Move the x terms to the left and change the sign

x + 2x = 6

3x = 6

x = 2

Now that you know x, substitute them back into the first y = 2x

y = 2(2)

y = 4

x = 2, y = 4

total = principal × ( 1 + rate ) ^ years

total = 600 * (1.04)^5

total = 729.99

answer is c
