Answer: -3

Step-by-step explanation:

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

19+12k=−k−20

Step 1: Simplify both sides of the equation.

19+12k=−k−20

19+12k=−k+−20

12k+19=−k−20

Step 2: Add k to both sides.

12k+19+k=−k−20+k

13k+19=−20

Step 3: Subtract 19 from both sides.

13k+19−19=−20−19

13k=−39

Step 4: Divide both sides by 13.

13k /13 =  −39/13

Solve for<br> a. 7a-2b = 5a+b
Stels [109]
<span>So we have a problem with two unknows and one equation. We have to express one over the other like this: 7a - 2b = 5a + b. First we separate one kind on the left side and the other kind on the right side: 7a - 5a = b + 2b. Then: 2a = 3b. Now we divide both sides by 2 and get: a= 3b/2.</span>
