Answer:
x = -6
Step-by-step explanation:
We have to find the value of x in given equation [tex]3 -2x = 15[/tex]
Step 1 : We have to eliminate 3 from LHS
We proceed this by subtracting 3 from both the sides to balance the equation
[tex]3 - 2x = 15\\3 - 3 -2x = 15 - 3\\-2x = 12[/tex]
Step 2: Now, we have to eliminate -2 from LHS
We proceed this by dividing both sides by -2
[tex]-2x = 12\\\frac{-2x}{-2} = \frac{12}{-2} \\x = -6[/tex]
Therefore we have x =-6
