In state whether the statements are True or False.
A number x divided by 7 gives 2 can be written as x +1/7 = 2.
In state whether the statements are True or False.
12 is a solution of the equation 4x – 5 = 3x + 10.
Any value of the variable which makes both sides of an
equation equal, is known as a ______ of the equation.
Which of the following equations can be formed using
the expression x = 5:
(a) 2x + 3 = 13 (b) 3x + 2 = 13
(c) x – 5 = 1 (d) 4x – 9 =21
–1 is not a solution of the equation
(a) x + 1 = 0 (b) x – 1 = 2 (c) 2y + 3 =1 (d) 2p + 7 = 5
