2x-6y=12
x+3y=5
If x = tan , y = tan 2 , z = sec 2 , then which one of the following is true:
3x+2y+z=3
2
𝑥
+
𝑦
𝑧
=
0
2x+y+z=0
6
4
6x+2y+4z=6
0,5 x 3600
3y + 8x = 22
y + 6x + 9
solution for y in the equation 5y-7=185y-7=185y-7=18
2x - 5y = 11
x - 4y = 4
solve using simultaneous equations using the equating method
2036k + 509l = 1
(8x^6y^-15z^3)^(2/3)
2x-y
