x and y are two mystery numbers.
If x is five less than two times the value of y, write an equation to represent the value x.
x = 2y - 5
In this system of equations, what number should I multiply the first equation by to eliminate the x's, if I want subtract equation 2 from equation 1?
3x + 15y = 2
12x + 7y = 9

Nana ate 50 mores pieces of melon than Jalen ate at lunch yesterday. Jalen and Nana ate a total of 64 pieces of melon at lunch. Set up a system of equations represent this scenario.
Let n = the number of melon pieces Nana ate
Let j = the number of melon pieces Jalen ate
n = 50 + j
n + j = 62
Use substitution to solve for y in this system of equations (you do not need to solve for y):
9x+3y=15
y-x=5
x = 5/2

How many solutions does this system of equations have?
4x - 250y - 18x + 5(100y) = -25x + 80
250y + 11x - 80 = 10
