# Simplify the following algebraic expressions: (a) 6a 7a + 2a (b) 10x 3x + 7x 13x

## Question:

Simplify the following algebraic expressions:

(a) 6a − 7a + 2a

(b) 10x −3x + 7x −13x

(c) (7a + 3b) − (3a − 5b)

(d) (m − n) + (2m − 2n) − (5m − 7n)

(e) 5a + b − (2a + 3b)

(f) 3x + 2y − [15x + 3y − (9x − 2y)]

(g) 7p − 5q + [2p − 3q − (14p − 6q)]

(h) 5x − 6y − (−2x − 3y)

(i) (a + 2b + 3c) − (a − 2b − 3c)

(j) (x + 2y + 3z) − (x − 2y + 7z)
