Question

The linear equation for 2 more than the sum of a and 4 is 8 wil be-
(i) 2a + 4 = 8
(ii) 2 (a + 4) = 8
(iii) (a + 4) + 2 = 8
(iv) a +4=8​

Answer 1

Hey

I think the answer is option (iii)

(a+4) + 2= 8

Answer 2

The linear equation for 2 more than the sum of a and 4 is 8 wil be (a + 4) + 2 = 8

Given :

The statement " 2 more than the sum of a and 4 is 8 "

To find :

The linear equation for 2 more than the sum of a and 4 is 8 wil be-

(i) 2a + 4 = 8

(ii) 2 (a + 4) = 8

(iii) (a + 4) + 2 = 8

(iv) a + 4 = 8

Solution :

Step 1 of 2 :

Define Linear Equation

A linear equation is an algebraic equation consisting of variables and constants and equality sign in which each term has an exponent of one

Step 2 of 2 :

Find the linear equation

Here the given statement is " 2 more than the sum of a and 4 is 8 "

The variable involved is a

The sum of a and 4 = a + 4

Now 2 more than the sum of a and 4 = (a + 4) + 2

It is given that 2 more than the sum of a and 4 is 8

So the equation formed is

(a + 4) + 2 = 8

Which is the required linear equation

Hence the correct option is (iii) (a + 4) + 2 = 8
