Solution for 1.2x-(x+y)-3=0.75y-(x+y)-3 equation:


Simplifying
1.2x + -1(x + y) + -3 = 0.75y + -1(x + y) + -3
1.2x + (x * -1 + y * -1) + -3 = 0.75y + -1(x + y) + -3
1.2x + (-1x + -1y) + -3 = 0.75y + -1(x + y) + -3

Reorder the terms:
-3 + 1.2x + -1x + -1y = 0.75y + -1(x + y) + -3

Combine like terms: 1.2x + -1x = 0.2x
-3 + 0.2x + -1y = 0.75y + -1(x + y) + -3
-3 + 0.2x + -1y = 0.75y + (x * -1 + y * -1) + -3
-3 + 0.2x + -1y = 0.75y + (-1x + -1y) + -3

Reorder the terms:
-3 + 0.2x + -1y = -3 + -1x + 0.75y + -1y

Combine like terms: 0.75y + -1y = -0.25y
-3 + 0.2x + -1y = -3 + -1x + -0.25y

Add '3' to each side of the equation.
-3 + 0.2x + 3 + -1y = -3 + -1x + 3 + -0.25y

Reorder the terms:
-3 + 3 + 0.2x + -1y = -3 + -1x + 3 + -0.25y

Combine like terms: -3 + 3 = 0
0 + 0.2x + -1y = -3 + -1x + 3 + -0.25y
0.2x + -1y = -3 + -1x + 3 + -0.25y

Reorder the terms:
0.2x + -1y = -3 + 3 + -1x + -0.25y
