Answer:

1 =x

Explanation:

30 - 3x = 15 + 12x

Add 3x to each side

30 - 3x+3x = 15 + 12x+3x

30 = 15x +15

Subtract 15 from each side

30-15 = 15x+15-15

15 =15x

Divide each side by 15

15/15 = 15x/15

1 =x

Answer:


x=1

Explanation:

So we have the equation:


30-3x=15+12x

First, let's add 3x to both sides. The left side cancels:


30=15+15x

Now, subtract 15 from both sides. The right cancels:


15=15x

Divide both sides by 15:


x=1

So, the value of x is 1.

And we're done!
