lets call the one number X and the other Y so y equals 3X so 3X plus X equals 84 so 4X equals 84 we divide by 4 so x equals 21 so y equals 21 times 3 equals 63 so the two numbers are 63 and 21
please give me answer
It is y = 0
The z score, for a value y, is (y - 18.6)/4
i y=use Z-test
-y + y equals 0.
y= -2x
b = y - mx.
y=5-x
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
y=5
many solutions
y + y + 2 = 182y + 2 = 182y = 16y = 8whew !
7x + y = 4y = 4 - 7x
8
i have no clue what the answer is
