If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
Answer:
5.375676
change the divisor 11.1 to a whole number by moving the decimal point 1 placesa to the right. then move the decimal point in the dividend the same. then you have 596.7/111=5.375
x=(k-c)/6
6x+c=k
subtract c from both sides
6x=k-c
divide by 6 on both sides
x=(k-c)/6
When given a literal equation, you will often be asked to solve the equation for a given variable. The goal is to isolate that given variable. The process is the same process that you use to solve linear equations; the only difference is that you will be working with a lot more letters, and you may not be able to simplify as much as you can with linear equations.
2: x = -5/3 ; y = -4/3 (-5/3, -4/3)
