-3\6 h - 7\2 +1\2 =7\4
-3\6 h -6=-7\4
-3\6 h =-1\4
h= 14\36
h=7\18
Answer:
x = -6 ; y = -1
Step-by-step explanation:
2 x - y = - 11 .........equ No 1
- 2 x - y = 13 .........equ No 2
Adding equ No. 1 and equ No. 2
- 2 y = 2
∴ y = - 1
substituting y = -1 in equ no 1
2 x - ( -1) = -11
2 x + 1 = - 11
2 x = -11 - 1
2 x = -12
∴ x = -6
x = -6 ; y = -1
Answer:
linear
Step-by-step explanation:
since theres a constant change of 2x, its a linear relationship
Answer:
Infinitely many solutions.
Step-by-step explanation:
-t=9(t-10)-t=9(t-10)
-t=9t-90-t=9t-90
-t=8t-90=9t-90
8t-(-t)-90=9t-90
8t+t-90=9t-90
9t-90=9t-90
