7x-3y=-14,3x+y=-22
Given that y varies inversely as x $a^{b}$ and that y=12 when x =2 ,and y=3 when x=4. Find the equation connecting y and x
4y-3x=34,x+6y=18
10 x1 + 2x2 =84
8x1 + 4x2 = 120
5x=67-2y,3y=3x+6
solve by using formula:x+3/2x-7=2x-1/x-3
if B:C=2:5
A:C=5:6
then A:B:C=?
\log _2\left(x+1\right)-4\log _4\left(x^2\right)+3\log _2\left(x\right)
5x-6y=18,2x-y=17
