Final answer:
To solve the equation 4x + 8 = 7.2 + 5 for x, combine like terms, isolate the variable, and divide by the coefficient. The solution for x is 1.05.
Step-by-step explanation:
To solve for x in the equation 4x + 8 = 7.2 + 5, we'll follow several steps:
First, combine like terms on the right side of the equation: 7.2 + 5 = 12.2.
The equation now reads 4x + 8 = 12.2.
Next, subtract 8 from both sides to isolate the term with x, resulting in 4x = 12.2 - 8, which simplifies to 4x = 4.2.
Finally, divide both sides by 4 to solve for x, which gives us x = 4.2 / 4 or x = 1.05.
Therefore, the solution for x is 1.05.
