Answer:
x = 3 and y = 0
Step-by-step explanation:
4x + 2y = 12
x – y = 3
solving substitution method,
x – y = 3
x = 3 + y
substitute this in the first equation
4(3+y) + 2y = 12
12 + 4y + 2y =12
12 + 6y = 12
6y = 12 - 12
6y = 0
y = 0
x = 3 + y
= 3 + 0
= 0
x = 3 and y = 0
Answer:
20
Step-by-step explanation:
its a pattern. the top goes up by three's so if it goes from 12 to 30 the d8 should go to 20 because if you add 3 to 12 to get it higher than you add 2 to 8 to get it higher.
