Question

Solve for the variable. 5 - x = 16

Answer 1

5x^2-4= 16 x^2-9x+20=0 9/10 = C/48 3x^2+x-1=0 and 9 - 3x < 4 (-x+1)

Answer 2

5-x=16 subtract 5 from both sides
-x=11 multiply both by -1
x=-11

Answer 3

5x + 2y = 16 ------------- (1)
3x + 4y = 18 ------------- (2)

eq(1) X 2 - eq(2) we get,

10x + 4y - 3x - 4y = 32 -18
7x = 14
x =2

putting the value of x in eq(1)

10 + 2y =16
2y = 6
y =3


therefore,
x = 2 and y = 3
