Y = x + 3 . . . (1)
4x + y = 18 . . . (2)
Putting (1) into (2) gives
4x + x + 3 = 18
5x = 18 - 3 = 15
x = 15/5 = 3
x = 3
y = x + 3 = 3 + 3 = 6
Solution = (3, 6)
Answer:15 times
Step-by-step explanation:
For the 3 batches it is 3 x 5/4 (5/4 is how much each batch costs)=15/4
And you must divide 15/4 by 1/4 or multiply it by 4 crossing out the denominator giving you your answer 15
Y/3 + 1/4 = 5/12
4y/12 + 3/12 = 5/12
4y/12 = 2/12
4y = 2
/4 /4
y = 1/2
Therefore y = 1/2
