Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer:
y = 3x
Step-by-step explanation:
y = 13
x= 4
here
y∝x
that is
y= k x where k is constant
Since the equation is in the form
we know that


so we can write this
y = 3.23 x ≅ 3x
