First solve one of the two equations (whichever is easier) for either x or y, whichever variable is easier. Let's say you solved for x. Then plug what x equals into the 2nd equation as x. So if you got x = 2y + 1, plug that into your other equation and solve for y (you should get a number value).
Now take whatever y equals and plug that back into what you got when you solved for x (the x = 2y + 1) to get what x equals.
Answer:
7/50 meter
Step-by-step explanation:
Total piece of string = 7/8 meter
Used string = 1/5 of the piece of string
Used string =
1/5 of 7/8 meter
= 1/5 × 7/8
= 7/40 meter
Balance = Total string - used string
= 7/8 - 7/40
= 35-7/40
= 28/40
Balance = 28/40 meter
cuts the rest into 5 equal parts. What is the length of the pieces.
28/40 ÷ 5
= 28/40 × 1/5
= 28 / 200
= 7/50 meter
Length of each piece = 7/50 meter
