This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

Do the math inside parentheses first
95 x 5 = 475
Now, take away the parentheses
2 + 475 = 477
The answer is 477
<h3><u>The value of g(f(4)) is -9.</u></h3>
f(x) = x - 7
g(x) = x^2
g(f(4))
f(4) = 4 - 7 = -3
g(-3) = -3^2 = -9
