Question

What is the value of s in the equation 7 = -10s - 3?

Answer 1

s = -1

Explanation:

What is the value of s in the equation 7 = -10s - 3?

7 = -10s - 3

10s = -3 - 7

10s = -10

s = -10 : 10

s = -1

---------------

check

7 = -10 * (-1) - 7

7 = 10 - 7

7 = 7

the answer is good

Answer 2

s = -1

Explanation:

7 = -10s - 3

==> add 3 to both sides

10 = -10s

==> divide both sides by -10

-1 = s
