It is an equation and the value of x is 8
The diagonals will be equal and so: 4x-47 = 2x+31 => 4x-2x = 31+47 => 2x = 78 Therefore the value of x is: x = 78/2 => x = 39
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
x = number Four times the number (4x) is the same as the number increased by 78 (x + 78). Since they are both equal, then 4x = x + 78 4x - x = 78 3x = 78 x = 26
81 - 78 = 3
