You can put this solution on YOUR website! subtract
.
3x + y = 2
4x + y = 20
--------------
-x = -18
x = 18
.
or multiply the first equation by 4 and the second by 3 and then subtract
.
12x + 4y = 8
12x + 3y = 60
--------------
y = -52
.
check these values
.
3x + y = 2 ??
3(18) + (-52) = 54-52 =2
correct
.
4x + y = 20
4(18) + (-52) = 72-52 = 20
correct.
.
Answer: x=18, y=-52
.
Done.
