Can someone me. this is one question.

To substitute into the second equation, you need to get y by itself on one side,

-y = -22x - 23

You would now divide both sides by -1,

y = 22x + 23

Now you can plug in this equation for y,

11x + 12(22x+23) = 1

Now apply 12 to both 22x and 23,

11x + 264x + 276 = 1

Now combine the x's since they are like terms,

275x +276 = 1

Now subtract 276 from both sides to get 273x by itself,

275x = -275

Now divide -275 by 275,

x=

This gives you -1

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.
