You can put this solution on YOUR website! 6x + 5y = -8
-5x + y = 48
:
We can use the 2nd equation for substitution in the 1st equation, write the 2nd equation:
y = 5x + 48
:
Substitute (5x+48) for y in the 1st equation
6x + 5(5x+48) = -8
6x + 25x + 240 = -8
6x + 25x = -8 - 240
31x = -248
x =
x = -8
find y
y = 5(-8) + 48
y = -40 + 48
y = +8
:
Check our solutions in the 1st equation
6x + 5y = -8
Replace x and y
6(-8) + 5(8) = -8
-48 + 40 = -8; confirms our solution of x=-8. y=+8
