To solve for x:
(6 + 15) : x = 721 : x = 7x = 21 / 7x = 3
To solve for X:
X : (240 + 20) = 2X : 260 = 2X = 2 * 260X = 520
To solve for Z:
Z • (108 - 100) = 64Z • 8 = 64Z = 64 / 8Z = 8
To solve for Y:
Y : (180 - 12) = 4Y : 168 = 4Y = 4 * 168Y = 672
To solve for x:
(6 + 15) : x = 7
21 : x = 7
x = 21 / 7
x = 3
To solve for X:
X : (240 + 20) = 2
X : 260 = 2
X = 2 * 260
X = 520
To solve for Z:
Z • (108 - 100) = 64
Z • 8 = 64
Z = 64 / 8
Z = 8
To solve for Y:
Y : (180 - 12) = 4
Y : 168 = 4
Y = 4 * 168
Y = 672
