Answer :
Answer: 1045 cm of red ribbon and 1045 cm of yellow ribbon
Step-by-step explanation:
Let R represent the amount red ribbon and Y represent the amouont of yellow ribbon.
- bought the same lengths of red and yellow: R = Y
- after used 286 of red, yellow is 5 times the remaining red; 5(R - 836) = Y
Use substitution method to solve:
5(R - 836) = R
5R - 4180 = R distributed 5 on the left side
4R - 4180 = 0 subtracted R from both sides
4R = 4180 added 4180 to both sides
R = 1045 divided both sides by 4
