Question

plz send answer in step by step explanation also in unitary method only solve with the equation given.​​

Answer 1

Answer:

x=30

Step-by-step explanation:

lets say we have an angle x

then the remaining angle in the supplementary will be (180-x)

and relation between those two angles is given as

x=1/5(180-x)

as requested lets do step by step..

we will use the following idea

a=1/5(b-a)

5a=b-a

now, simply move the 5 up to the left hand side of the equation as it is already taken as common outside.

after that, we will arrive at something like this

5x=180-x

now bring "like terms to one side"...

here 5x and x are like terms so

When you are changing the position of a term/variable from right to left or left to right be careful to change its sign respectively.

remember this!

across the equal to symbol when you interchange

+ becomes - or addition becomes subtraction and vice versa

and multiplication becomes division and vice versa

so

5x+x=180  

6x=180

x=180/6

x=30
