If x=7and = -2, determine the value of 6x-4y

It's 50. Just multiply 6 times 7 and you get 42. Then you multiply 4 times - 2 which is - 8. Then you subtract the products and you get 50. Your welcome.

the answer is 50

Step-by-step explanation:

first you plug in the x and y in the equation, making it 6 (7) = -4 (-2) then, you multiply the numbers together, making the equation 42+8. finally, you add those numbers together, giving you the answer 50
