Given the equation 5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13
Given the equation |
Homework Answers
Multiply factors.
-15 x - 10 - x + 3 = - 16 x - 20 + 13
Group like terms.
- 16 x - 7 = - 16 x - 7
Add 16x + 7 to both sides and write the equation as follows
0 = 0
The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.
