Where possible, simplify the following expressions by adding or subtracting like terms.

Question

a. 7t—2t
b. 120b 2ab
c. 8fg — 2fg

Answer 1

a. 7t - 2t = 5t

b. 120b - 2ab = 120b - 2ab

c. 8fg - 2fg = 6fg

Answer 2

Where possible, simplify the following expressions by adding or subtracting like terms.
a. 7t—2t
b. 120b 2ab
c. 8fg — 2fg
d. 4e-e
e.6t+t

Answer 3

a. 7t - 2t = 5t
b. 120b + 2ab = 122b + 2ab
c. 8fg - 2fg = 6fg
d. 4e - e = 3e
e. 6t + t = 7t

Answer 4

Where possible, simplify the following by adding or subtracting the like terms
a.f+4f
b.6y-6y
c.4x+14x
d.3m+16m-7m
e.6a+4a-2a

Answer 5

a. f + 4f = 5f
b. 6y - 6y = 0
c. 4x + 14x = 18x
d. 3m + 16m - 7m = 12m
e. 6a + 4a - 2a = 8a

Answer 6

Simplify the following expressions (if possible).
a. 240b ab — 7
b. 5y+y—3y
c. 5t+Ss
d.
e. 7r+2r+5r—r

Answer 7

a. 240b ab - 7
Since there is no common factor or like term in the expression, it cannot be simplified further.

b. 5y + y - 3y
Combining the like terms, we have:
5y + y - 3y = (5y + y) - 3y = 6y - 3y = 3y

c. 5t + Ss
Since there is no common factor or like term in the expression, it cannot be simplified further.

d. The expression is missing, please provide the expression.

e. 7r + 2r + 5r - r
Combining the like terms, we have:
7r + 2r + 5r - r = (7r + 2r + 5r) - r = 14r - r = 13r

Answer 8

d. 4t+8t-3+2t

Answer 9

d. 4t + 8t - 3 + 2t
Combining like terms, we have:
4t + 8t + 2t - 3 = (4t + 8t + 2t) - 3 = 14t - 3
