Carol and Clyde have painted a fence. Both have painted a triangular number of slats. if Carol painted 98 more slats than Clyde and she has painted less than 200 slats, how many slats did they paint together

Heya dear

df =

both have same length

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
