Question

Find the values of the following:
a 2x - 3y when x = 3, y = -2
b. azt.b - 2c when a =3) b = 2, c = -1
2p+ 2q - 4r when p = 1,9 = 2, r = -6 d. 2ab + 3bc - 4ac when a = 1, b = -2, c = 3
p-q-r when p = 1, q = -1, r=-3 f. 3xy - 4yz - xz when x = 1, y = -2, z = -3
And the value of the following expressions:
2x - 7x + 5 when x = 3
b. 3x2 - 4x2 + 5x when x = -2
+ x - 5x + 7 when x = -3
d. 3x2 - 4x + 7 when x = 1
2-3x + 7x - 12 when x = -2 f. 2 - - x + 3 when x = -1
