How do I solve this equation: 7x-4=3+8x

x=-7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x−4=3+8x

7x+−4=3+8x

7x−4=8x+3

Step 2: Subtract 8x from both sides.

7x−4−8x=8x+3−8x

−x−4=3

Step 3: Add 4 to both sides.

−x−4+4=3+4

−x=7

Step 4: Divide both sides by -1.

−x/−1=7/−1

x=−7
