Answer:
k=16
Step-by-step explanation:
Combine all the like terms
- 2k+10+5k-25+3k+35 =180
- (2k+5k+3k) + (10-25+35) = 180
- 10k + 20 = 180
Solve for k by subtracting 20 on both sides and then dividing by 10 on both sides
cross multiply to find your answer
x/250 = 20/100
250 X 20= 5000
5000=100x
x = 50
250 - 50 = 200
hope this helps :)
