"three times the sum of a number and 4 is 3." translates to 3%28x%2B4%29=3


3%28x%2B4%29=3 Start with the given equation.


3x%2B12=3 Distribute.


3x=3-12 Subtract 12 from both sides.


3x=-9 Combine like terms on the right side.


x=%28-9%29%2F%283%29 Divide both sides by 3 to isolate x.


x=-3 Reduce.
