Answer:
4
Step-by-step explanation:
Based on the equation you are given, calculate the values of a, b, and c. Then substitute each value for the corresponding variable and use the correct order of operations.
a = 2b = 3c = 6
a = 6
2b = 6, so b = 3
3c = 6, so c = 2
a + 2b - 4c =
= 6 + 2(3) - 4(2)
= 6 + 6 - 8
= 12 - 8
= 4
