a) 4x + 2 = 14
b) x - 7 = 5 - 2xc) 3a - 8 = a + 12
The equation 4x + 2 = 14 is true only when x = 3,Similarly, x - 7 = 5 - 2x is true only when x = 4, and
3a - 8 = a + 23 is true only when a = 10.The two expressions (LHS and RHS) are equal only for a particular value of the variable (x). These equations are called equations of condition. An equation of condition is generally referred to as an equation.
