1. three times a minus four = 3 X a - 4

2. a number c increased by two = c + 2

3. a number x less than 7 = x -7

4. ten plus a number y = 10 + y

5. the product of c and four = c X 4

translate into a verbal phrase

1. 9+7× =nine plus seven and a number x

2. 2×+3y = two and a number x increase by three and a number y

3. 2×-4 = two and a number x decrease by four

4. 7×+4 = seven and a number x plus four

5. P=4s = a number P is equal to four and a number s

simplicity the following numerical expression

1. 36+6+5×4 = 62

2. 35-(4+9) = 30

3.12×5+(15-3) = 72

4. 25-4+10 = 31

5. 100+25+7×3 = 346

find the sum

1. -6r, 5r, 7r and 4r = 10

2. 475t and -629t = -154

find the difference

3. -52d-73d = -125

4. 29z-54z = -25
