Note::
Problem2.2d:
Answer: x=-59,042.
Solution:
isolated.
x-7=-59,049
x=-59,042
x. If the left side of the equation equals the right side of the equation
after the substitution, you have found the correct answer.
Left side:
Right side: You can also check the answer by graphing
(the left side of the original equation minus the right side of the original
equation). The solution will be the x-intercept. The x-intercept (and
hence the solution) on the graph is -59,042.
