Question

Given 3X=-15
Prove X =-5

Answer 1

Answer:

X = -5

Step-by-step explanation:

3X=-15

Lets solve the equation for x.  We will isolate x by dividing each side by 3

3X/3 = -15/3

X = -5

Answer 2

Method 1:

Solve the equation

3x = -15     divide both sides by 3

3x : 3 = -15 : 3

x = -5

Method 2:

Put the value of x to the equation:

L = 3(-5) = -15

R = -15

L = R    CORRECT
