1 real solution, x=2
Step-by-step explanation:
Let's solve for x and see how many solutions exist.
To solve for x, we must get x isolated. To do this, perform the inverse operation to both sides of the equation.
8-4x=0
4x is being subtracted from 8. The inverse, or opposite, of subtraction is addition. Add 4x to both sides.
8-4x+4x=0+4x
8=0+4x
8=4x
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
8/4=4x/4
8/4=x
2=x
x is equal to 2, therefore there is 1 real solution.
