What inverse operation is used to solve the equation?
someone pls me

x − 2 = 5
a) add 2 to both sides
b) multiply by 2 on both sides
c) divide by 2 on on both sides
d) subtract 2 from both sides

a

Step-by-step explanation:

to isolate x, we have to add two to both sides so the - 2 gets cancelled out.

y=x+9

?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
