Question

If y= 5x-2 and x= 4b+3 then y is equivalent to which of the following

Answer 1

y = 20b + 13

Explanation:

From the above, we want to get y

Using the given d value, we simply proceed to substitute

y = 5x-2

x = 4b + 3

Substituting x-values, we have

y = 5(4b + 3)-2

y = 20b + 15-2

y = 20b + 13
