Answer:
Step-by-step explanation:
3x - 4y = -11
x - 2y = -5
Compare the coefficients of the variables.
The coefficients of the x terms, 3 and 1, are multiples of each other.
The coefficients of the y terms, -4 and -2, are also multiples of each other.
That makes it easy to eliminate either variable.
I'll eliminate the y variables. Multiply the second equation by -2, then add it to the first equation:
₋-2x + 4y = 10
3x - 4y = -11
--------------------
x + 0y = -1 , so x = -1.
Substitute -1 for x in either equation and solve for y:
3(-1) - 4y = -11
y = 2
(x,y) = (-1, 2)
24 divide by 3 is 8
