The sum of twice a number and three times another number is 120. Four times the first number plus the second number is 64. Calculate the value of the two numbers.
-----
Equations::
2x + 3y = 120
4x + y = 64
---------------------
Modify for elimination:
2x + 3y = 1203
12x + 3y = 192
------
Subtract and solve for "x"::
10x = 72
x = 7.2
------
Solve for "y"::
y = -4x + 64
y = -28.8 + 64
y = 35.2
