Question

What is the value for x?

Btw plis add the explanation I would love to know the process of getting the answer for future references :) thx!

Answer 1

x =
`(11y)/(7)` +
`(8)/(7)`

Step-by-step explanation:

7x - 3 = 11y + 5

7x = 11y + 8

x =
`(11y)/(7)` +
`(8)/(7)`

Answer 2

Answer:

Step-by-step explanation:

Since this is an equilateral triangle, all the sides and the angles are equal to each other.

=> angle L = Angle N = Angle M

And if Angle N = 7x - 3

Thus all the other angle also = 7x - 3

And the sum of interior angle in a triangle is 180 degree.

We can write an equation:

Angle L + Angle N + Angle M= 180
7x - 3 + 7x - 3 + 7x - 3 = 180
21x - 9 = 180
21x = 180 + 9
21x = 189
x = 9

Therefore, x = 9
