Question

(30-a)+(125+2a)=180​

Answer 1

Answer:

30-a+125+2a=180

155+a=280

a=280-155

125

Answer 2

Answer:

We will get the value of a$=25$

Explanation:

In accordance with the information provided in the question,

Given the data in question (30-a)+(125+2a)=180​

Simplifying further we get,

$30-a+125+2a$$=180$

$155+a=180$

We have find the value of" a" in the above question.

Here we will use the transposition method.

Hence, for solving the above equation, we will solve it by separating the like terms at one side ,  

So, we will shift 155  from LHS to RHS the sign will change from positive to negative,

As we get,

$155+a=180\\a=180-155$

$a=25$

Hence we will get the value of a$=25$
