what is the ratio for 2:1 for 27 pupils
x=2 x−1x_{-1}x−1
what is the lowest common multiple of 2,3,4 and 9
x + 2y = 7
2x - 2y + -10
2x - y = 26
y - 10 = -x
a^4 + 4.6*a^3-31.5*a^2-164*a-201=0
lcm of 11 and 16
3x + 3y = 54
x + 3y = 58
₹1,000 * [((1 + 0.00833)^12 - 1) / 0.00833] * (1 + 0.00833)
4x - y = - 16
2x + y = 11
