Answer 1

Answer:

k = 11.87

Step-by-step explanation:

Because the two expressions should be equivalent, set the two expressions equal to each other.

$-10.5x+k=-2.1(5x-3.7)+4.1$

Begin simplifying the equation and solve for k.

$-10.5x+k=-10.5x+7.77+4.1$ (distributive property)

$-10.5x+k=-10.5x+11.87$ (combine like terms - 7.77 + 4.1)

$k = 11.87$ (add 10.5x to both sides to combine like terms -- the x values cancel out because -10.5x+10.5x = 0.  Therefore, you are left with k = 11.87)
