Question

4x-y=23 and 3x-2y+4=0 the mean value of x is​

Answer 1

Answer:

value of x equals 10

value of y equals 17

Step-by-step explanation:

$4x - y = 23 \\ y = 4x - 23 \\ substitute \: in \: second \: equation \\ 3x - 2(4x - 23) + 4 = 0 \\ 3x - 8x + 46 + 4 = 0 \\ - 5x + 50 = 0 \\ - 5x = - 50 \\ x = 10$

substitute the value of x in

$y = 4x - 23 \\ = 4(10) - 23 \\ 40 - 23 = 17 \\ y = 17$

verification

$3(10) - 2(17) + 4 \\ =30 - 34 + 4 \\ = 34 - 34 = 0$
