Answer:
the answer would be -4
Step-by-step explanation:
just replace the variable y with two in the expression and solve
3(2)^2-5*2-6
Answer:
(-1,-4)
Step-by-step explanation:
6m-5n=14 equation 1
2m+2n= -10 equation 2
using equation 2 we have
2m=-10-2n
m=-5-n equation 3
using equation 1 we have
6*(-5-n)-5n=14
-30-6n-5n=14
-11n=14+30
-11n=44
n=-44/11
n=-4
using equation 3
m=-5-n
m=-5-(-4)
m=-1
finally we have
(-1,-4)
