Hello,
Pls post the full question next time so that we can make sure what is expected.
I assume that you want to solve for (x,y)
(1) 2x + 3y = 7
(2) 3x + 2y = 8
2*(2)-3*(1) gives
2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5
6x - 6x + 4y -9y = -5
-5y=-5
y = 1
and we can replace in (1)
2x + 3*1 = 7
2x = 7 - 3 = 4
x = 2
hope this helps

Answer:
x = 8
Step-by-step explanation:
The line segment inside the triangle is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
( cross- multiply )
6x(11x - 4) = 63x² ← distribute left side
66x² - 24x = 63x² ( subtract 63x² from both sides )
3x² - 24x = 0 ← factor out 3x from each term on the left side
3x(x - 8) = 0
Equate each factor to zero and solve for x
3x = 0 ⇒ x = 0
x - 8 = 0 ⇒ x = 8
But x > 0 , then x = 8
