Find the value of 3a − 2b, when a = 8 and b = 10

If a = 3, b = 0, c = 2 and d = 1, find the value of abc − bcd + cda

Simplify:

x − (x − y) − (− x + y)

Simplify:

3x + (8x − 5x) − (7x − x)

Insert the bracket as indicated:

ab + 2bc − 3ac = 2bc − (...............)

If x = 2, y = 3 and z = 4, find the value of 3x² – 4y² + 2z².

If x = 3, y = 2 and z = 1; find the value of xy + y²z – 4zx

If P = − 12x² – 10xy + 5y², Q = 7x² + 6xy + 2y², and R = 5x² + 2xy + 4y²; find Q + P

If P = − 12x² – 10xy + 5y², Q = 7x² + 6xy + 2y², and R = 5x² + 2xy + 4y²; find P + Q + R

Multiply and then evaluate:

(x² – y) and (xy – y²); when x = 1 and y = 2.
