If x+y=nx+z then x is equal to

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Order the equations from least to greatest based on the number of solutions to each equation.-4^x -1 = 3^(-x) – 2 -3x + 6 = 2^x+13^x – 3 = 2x - 2
