To simplify the expression 3X + 5Y - XY when X = 7 and Y = 3, substitute the values in the expression and solve:
= 3(7) + 5(3) - 7(3)
= 21 + 15 - 21
= 36 - 21
= 15
So, the simplified expression is 15 when X = 7 and Y = 3.
Therefore, the correct answer is:
c. 15
= 3(7) + 5(3) - 7(3)
= 21 + 15 - 21
= 36 - 21
= 15
So, the simplified expression is 15 when X = 7 and Y = 3.
Therefore, the correct answer is:
c. 15
