Solve for f:(i - 47/12) + f = 18 (i - 47/12) + f = f + (-47/12 + i): f + (-47/12 + i) = 18 Subtract -47/12 + i from both sides:Answer: f = 263/12 - i
Answer:
19 2/3
Step-by-step explanation:
32 ft minus 12 and 1/3 ft is 19 and 2/3 ft.
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14 Now add it up to the 2nd equation -4y-2x=-14 2y+2x=10 -------------- And now add them up -2y +0x=-4 ==> -2y=-4==> 2y = 4 & y=2 Last step: plug y into any equation & you will find x=3
