Hi There!

Evaluate 4x - 3y + (7x - 7y) when x = 6 and y = -1.

Remember to follow P.E.M.D.A.S

-------------------------------------------------

Solution:

= 4(6) - 3(-1) + (7(6) - 7(-1))

= 4(6) - 3(-1) + (42 - (-7))

= 4(6) - 3(-1) + 35

= 24 - (-3) + 35

= 21 + 35

= 56

-------------------------------------------------

Answer: C) 56
