8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.
Answer:
B: When one quantity is a constant multiple of the other
Answer: its a half a percent or 50%
Step-by-step explanation:
Hey, there!!
Given that:
y = 3x.........(i)

Putting the value of y in equation (ii)

=0


Therefore,
Either Or
(x+4)=0 (x-4)=0
x= -4 x= 4
so, x= (+ -)4
And if you wanna get value of y, just keep value of x in equation (i).
y= 3x
y= (3×4) or (3×-4)
y= 12 or -12
{As it is the quadratic equation it has two values. }
