Question

What is the value of k in the following equation?
2(4k + 5) + 3(3 – 3k) = 25

Answer 1

K = - 6

Explanation:

Let's solve your equation step-by-step.

2(4k+5)+3(3−3k)=25

Step 1: Simplify both sides of the equation.

2(4k+5)+3(3−3k)=25

(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)

8k+10+9+−9k=25

(8k+−9k)+(10+9)=25(Combine Like Terms)

−k+19=25

−k+19=25

Step 2: Subtract 19 from both sides.

−k+19−19=25−19

−k=6

Step 3: Divide both sides by -1.
