Question

Twice the sum of k and 9 is 4

Answer 1

-7

Explanation:

First, we need to write this an equation

2(k+9)=4

2k+18=4

-18 -18

2k=-14

/2 /2

k=-7

Answer 2

2(k + 9) = 4

Explanation:

Use distributive property.

2 x k = 2k

2 x 9 = 18

Equation:

2k + 18 = 4

Subtract 18 from both sides

2k = -14

Divide both sides by 2

k = -7
