Question

iv) Which of the following linear equation is in one variable:
a) 2 x + 5=6
e) a+ 6 =6b
b) X+1 = 6
d) x +y = 16

Answer 1

Answer:

It's a) 2x + 5 = 6

Step-by-step explanation:

a + 6 = 6b cannot be an option (It has 2 variables in it)

x + y = 16 also cannot be an option as it also have 2 variables in it i.e. x and y

2x + 5 = 6 have only 1 variable and it is in the standard form while x + 1 = 6 is not in it's standard form
