by the use of elimination method
make all coefficients of subject to be eliminated similar..by multiplying the coefficients with one another
for eqn(i)
5(-10y+9x=-9)
-50y+45x=-45
for eqn(ii)
9(10y+5x=-5)
90y+45x=-45
-50y+45x=-45
90y+45x=-45
...subtract each set from the other...
we get
-140y+0=0
y=0
from eqn(i)
10y+5x=-5
0+5x=-5
x= -1

D.$21.78
61 x (1/10)=
Or 61 x .1
The answer is 6.1
The answer is B
step by step explanation:
As function is = 4x
so
4x=-x+5
5x=5
x=1
