Let x represent one number and let y represent the other number. Use the given conditions to write a system of equations. Solve the system and find the numbers.
Three times a first number decreased by a second number is 88. The first number increased by twice the second number is 12.
What the first​ number?
x=
What is the second​ number?
y=
Solve the system by graphing
4x+y=8 and 8x+5y=28
Solve the system by the substitution method.
x+y= -8 and y= -3x
Solve the system by the substitution method.
y= -2x-6 and 5x -4y= -2
Solve the system by the addition method.
x+y= -7 and x-y= 3
Solve the system by the addition method.
4x+3y=12 and 3x - 3y=9
Solve the system by graphing.
-2x + 3y=12 and x - 3y= -9
