Question

Y-13x=-113 40x-3y=350

Answer 1

Ответ:

Пошаговое объяснение:

у=13х-113

40х-3(13х-113)=350

10х-39х+339=350

х=11

у=13*11-113=30

Ответ (11; 30)

Answer 2

To solve the system of equations:

1. Y - 13x = -113
2. 40x - 3y = 350

We can use the method of substitution or elimination. I'll demonstrate the elimination method.

First, let's rearrange equation 1 to solve for Y:

Y = 13x - 113

Now substitute this expression for Y in equation 2:

40x - 3(13x - 113) = 350

Simplify the equation:

40x - 39x + 339 = 350

Combine like terms:

x + 339 = 350

Subtract 339 from both sides:

x = 350 - 339 x = 11

Now substitute the value of x back into equation 1 to solve for Y:

Y = 13(11) - 113 Y = 143 - 113 Y = 30

Therefore, the solution to the system of equations is x = 11 and y = 30.
