Since 1 < x < 5, adding each side by a, where a is negative, gives
a > ax > 5a
and adding b to each side gives
a + b > ax + b > 5a + b
or
5a + b < ax + b < a + b
Since 7 < f(x) < 23, it follows that
5a + b = 7
a + b = 23
Solve for a by eliminating b :
(5a + b) - (a + b) = 7 - 23
4a = -16
a = -4
Solve for b :
-4 + b = 23
b = 27
Answer:
The solution of the given equations is (-3,2)
Step-by-step explanation:
<u>Step:1</u>
The Given equations are 2 x+3 y=0 .......(1)
x+2 y-1 =0.........(2)
<u>Step 2:-</u>
Solving<u> </u>both equations by using substitution method
multiply equation (2) with number '2' ,
2 x+4 y-2=0.......(3)
subtracting the equations (1) and (3) and cancelled 'x' terms
we get 

<u>Step 3:</u>-
substitute y= 2 in equation (1) we get




<u>Final answer</u>:-
The solution of the given equations is (-3,2)
