(-) (+) (-)
__________
1y = 34
y = 34
To find x
4x -2y = 60
4x -(2)(34) = 60
4x -68 = 60
4x = 60 + 68
4x = 128
x = 32
Answer:
x=32 ; y=34
Answer:
Step-by-step explanation:
4x - 2y = 60
4x - 3y = 26.....multiply by -1
-----------------------
4x - 2y = 60
-4x + 3y = -26 (result of multiplying by -1)
-----------------------add
y = 34
4x - 2y = 60
4x - 2(34) = 60
4x - 68 = 60
4x = 60 + 68
4x = 128
x = 128/4
x = 32
check...
4x - 3y = 26
4(32) - 3(34) = 26
128 - 102 = 26
26 = 26 (correct)
so x = 32 and y = 34.....or (32,34)
