Solve the equation

2x+x-3=3 (x+4) - 15

Step-by-step explanation:

2x+x-3=3 (X+4) - 15

2x+x-3=3x+12-15

2x+x-3-3x+3=0

0=0

Answer: All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

2x+x-3=3 (x+4) - 15

Step 1: Simplify both sides of the equation.

2x+x-3=3 (x+4) - 15

2x+x+-3 = (3) (x) + (3) (4) + -15 (Distribute)

2x+x+-3=3x+12+-15

(2x+x) + (-3) = (3x) + (12+-15) (Combine Like Terms)

3x+-3=3x+-3

3x-3=3x-3

Step 2: Subtract 3x from both sides.

3x-3-3x=3x-3-3x

-3=-3

Step 3: Add 3 to both sides.

-3+3=-3+3

0=0
