Find the value of p + 2q + 3r, when p = 1, q = 5 and r = 2

Find the value of 5x + 3y − 6z, when x = 3, y = 5 and z = 4

If a = 3, b = 0, c = 2 and d = 1, find the value of a² + 2b² − 3c²

Simplify:

x − (x − y) − (− x + y)

Insert the bracket as indicated:

2x − y + 2z = 2z − (....................)

If x = 3, y = 2 and z = 1; find the value of y^x

If x = 3, y = 2 and z = 1; find the value of 2x – 3y + 4z + 5

If x = 3, y = 2 and z = 1; find the value of y² – x² + 6z²

Multiply and then evaluate:

(4x + y) and (x – 2y); when x = 2 and y = 1.

Simplify:
