ОС.
13
OD. -3

Answer 1

13

Explanation:

because 13-20=-7

and -7x-5=35

so the answer is c

Answer 2

x = 13

Explanation:

Given:

–5(x – 20) = 35

Solve:

–5(x – 20) = 35

Distribute the equation:

{-5 × x = -5x}
{-5 × -20 = 100}

-5x + 100 = 35

Subtract both sides by 100

-5x + 100 = 35

-5x + 100 - 100 = 35 -100

Simplify

-5x = -65

Divide both sides by -5

-5x/5 = -65/5

Solution:

x = 13
