Ответ:
x = 6, y = 9 is the solution to the given system of equations.
Step-by-step explanation:
Here, the system of the equations is:
Now, substitute the value of y in the second equation, we get
⇒![33 + 1 = \frac{5x}{3} + 4x](/tpl/images/0351/4393/3f3e7.png)
or, [tex]\frac{5x + 12x}{3} = 34[/tex}
or, 17x = 3 x 34 = 102
So, x = 102 / 17 = 6
⇒x = 6 : putting this in (1),
y = -4x + 33 = - 24 + 33 = 9
Hence, x = 6, y = 9 is the solution to the given system of equations.
