Question

determine whether x=4 is a solution of the equation x+16 =20
​

Answer 1

Answer:

yes by putting value of x in equation, you will get 20=20.

which means 4 is a solution of given equation.

Answer 2

Answer:

X = 4

X+16=20

we will export 16 to 20

then we will do 20 -16

it will give 4

so if X =4

4 + 16 = 20
