Yes the ratio is right but.. were's the options? comment in my profile if you need help c:
First do 8 + 4 which is 12
Next do 12 times 2 which is 24
Final step is to do 24 divided by 1 which gets you 24
The answer is 24.
Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3
