Given: 2(x + y) = 5
Multiply both sides of the equation by 2.5 to get: 2.5[2(x + y)] = 2.5(5)
Simplify: to get: 5(x + y) = 12.5
Since we're also told that 5(x + y) = k, we can see that k = 12.5
Answer: 12.5

Multiply both sides of the equation by 2.5 to get: 2.5[2(x + y)] = 2.5(5)

Answer: 7.5
Hi shouldnt 2.5 * 5 = 12.5?
