Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
18.5=−4.5+7(k+6)
Step 1: Simplify both sides of the equation.
18.5=−4.5+7(k+6)
18.5=−4.5+(7)(k)+(7)(6)(Distribute)
18.5=−4.5+7k+42
18.5=(7k)+(−4.5+42)(Combine Like Terms)
18.5=7k+37.5
18.5=7k+37.5
Step 2: Flip the equation.
7k+37.5=18.5
Step 3: Subtract 37.5 from both sides.
7k+37.5−37.5=18.5−37.5
7k=−19
Step 4: Divide both sides by 7.
7k
