#1. 6k+8=-10
#2. 5z-5=15

I need to solve k and z

1. k= 6

2. z= 4

Step-by-step explanation:

1. Given equation is:

6k+8=-10

We will solve the equation.

Subtracting 8 from both sides

6k+8-8 = -10-8

6k = -18

Dividing both sides by 6

2. Given equation is:

5z-5=15

We will solve the equation.

Adding 5 on both sides

5z-5+5=15+5

5z=20

Dividing both sides by 5

Hence,

1. k= 6

2. z= 4

5-¹³ is the correct answer
