Question

What is 2k + 10 + 5k - 25 + 3k + 35 = 180?

Answer 1

k=16

Explanation:

2k+5k+3k-25+10+35=180

10k+20=180

10k=180-20

10k=160

k=16

Answer 2

k=16

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

• 10k=160
• k=16
