Question

Solve:-3x = 15 how do you solve this​

Answer 1

Hi, to find the answer here you need to divide both sides by -3 to isolate x.

-3x / 3 = x

15 / -3 = -5

Now the equation looks like x = -5. You can test to make sure that's correct before submitting by replacing x with -5 in the original equation, so -3(-5) = 15.

Hope this is helpful :)

Answer 2

-3x=15

Divide both sides by -3 to get + x

-3x/-3= 15/-3

Cross out -3 and -3 , divide by -3 and then becomes 1*1*x= x

x=-5

Answer: x= -5
