Multiply -5/8x^2y^3 by -16/15x^3y and verify your result for x = -1, y =2.
Answers
Answer:
We will explore our way through such a system: 3.1 + 5y – 2z = -7 -4x – 2y + z = -3 2.x – 3y 13 (a) Multiply both sides of the second equation in the system above by 2, and add this equation to the first equation to obtain a new equation. (If done correctly, the new equation you obtain will not have z in it.) (b) Note that the third equation in the original system and the new equation you obtained from (a) form a new system of two equations in x and y. Solve this system using a method you learned in the class. When you're done, you should have the numerical values for x and y. (c) Now substitute the values of x and y you found in (b) into one of the equations in the original system to find the value of z.
