Answer:
True
Explanation:
To know whether -2x + 4y = 14, where x = 5 and y = 6, we need to plug in 5 for x and 6 for y.
-2x + 4y = 14 Original equation
-2(5) + 4(6) = 14 Plug in 5 for x and 6 for y
-10 + 24 = 14 Multiply the number infront of the parentheses into it
14 = 14 Let 24 add itself to -10 on the left
This tells us it is true that -2x + 4y = 14, where x = 5 and y = 6.
