Question

Y’all give me dis answer to

Answer 1

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4     Eqn 1

4x+y = 1     Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

$4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3$

Putting y = -3 in equation 1

$x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1$

Hence,

The solution is: (1,-3)
