Which expression is equivalent to 13x - 2y -3 (x + 4y) with fewer terms?

Question

a) 16x - 14y
b) 10x - 10y
c) 10x - 14y
d) 16x - 10y

Answer 1

To simplify the given expression, we need to multiply the terms in the brackets by -3:

13x - 2y - 3(x + 4y) = 13x - 2y - 3x - 12y = (13x - 3x) + (-2y - 12y) = 10x - 14y

Therefore, the expression 13x - 2y -3 (x + 4y) simplified with fewer terms is:

c) 10x - 14y
