3x + y=11
-2x + y=1
Solve using substitution method
2 answers:
Step-by-step explanation:
here's the solution : -
=》3x + y = 11
=》y = 11 - 3x
now, plugging the value of y in equation 2
=》-2x + y = 1
=》-2x + 11 - 3x = 1
=》-5x = -10
=》x = 2
now, plugging the value of x as 2 in equation 1
=》3x + y = 11
=》6 + y = 11
=》y = 11 - 6
=》y = 5
Answer:
3x+yl=11
-2x+y=11
y=11-3x
-2x+11-3x=11
-5x=11-11
so x=0
y=11-0
y=11
