• 1/3

• 100/7

• 2

• 3

The equation having 1/4 as a solution is

• 4x + 1 = 2

• 11 – x = 7

• 8x + 1 = 33

• 3 + x = 8

Find the variable and constant in the algebraic expression y+21_________

• No variable

• No constant

• Variable is 21 & constant is y

• Variable is y & constant is 21

Form the equation for the following statement :

'one third of y is 25'

• y + 3 = 25

• y ⁄3 = 25

• 3y = 25

• y - 3 = 25

Write the statement for the equation

4p - 2 = 18

• four times a number p subtracted from 2 is 18

• 2 subtracted from four times a number p is 18

• 2 subtracted from a number p multiplyed by four gives 18
