Answer:
Hence, the equation is proportional.
Step-by-step explanation:
To test for proportionality ;
y = 12x
For a proportional relationship ;
y α x
y = kx ; where, k is the constant of proportionality.
From. The equation given
y = 12x ; 12 is thw proportionality constant.
5 + 2(3 + 2x) = x + 3(x + 1) (2nd one)
