Question

Find the values of a and b from the identity given below

3.5x - 5.5y + 1.5x - 0.5y ≡ ax - by

a = ................

b = ...............

Answer 1

a = 5.0

b = 6.0

Explanation:

3.5x - 5.5y + 1.5x - 0.5y == ax - by

collect like terms

we have,

3.5x + 1.5x -5.5y - 0.5y == ax - by

add the like terms

5.0x + (-6.0)y is equivalent to ax - by

i.e 5.0x == ax

-6.0y == -by
