When using substitution What is x and y for 3x plus 6y equals 48 -5x plus 6y equals 32?
Updated: 12/18/2022
3x + 6y = 48 .... Eq.1
-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32
Put the value of Eq.2 in Eq. 1
3x + 5x + 32 = 48
8x = 48 - 32
8x = 16
x = 16/8 ...... X = 2
To find the value of Y put the value of X in Eq.2
6y = 5x + 32
6y = 5(2) + 32
6y = 10 + 32
6y = 42
y = 42/6 ...... Y + 7
