Your family is traveling to Mexico on vacation. You have
saved $500 to spend. If 298 Mexican pesos is equivalent
to $25, how much money will you get when you
exchange your $500 for Mexican pesos?

5960 pesos

Step-by-step explanation:

We can write a proportion

298 pesos --- $25

x pesos      --- $500

x=298*500/25 = 298*20 = 5960 pesos

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
