Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d

Answer:

x=\frac{7}{5}

y=-\frac{22}{5}

Step-by-step explanation:

Given:

The given expressions are.

6x+y=4

x-4y=19

We need to find x and y values.

Solution:

Equation 1⇒ 6x+y=4

Equation 2⇒ x-4y=19

First solve the equation 1 for y.

6x+y=4

y = 4-6x --------(3)

Substitute y = 4-6x in equation 2.

x-4(4-6x)=19

Simplify.

x-(4\times 4 - 4\times 6x)=19

x-(16-24x)=19

x-16+24x=19

Add 16 both side of the equation.

25x-16+16=19+16

25x=35

x=\frac{35}{25}

Divide Numerator and denominator by 5.

x=\frac{7}{5}

Substitute x value in equation 3 and simplify.

y=4-6(\frac{7}{5})

y=4-\frac{6\times 7}{5}

y=4-\frac{42}{5}

y=\frac{5\times 4-42}{5}

y=\frac{20-42}{5}

y=-\frac{22}{5}.

Therefore, the value of x=\frac{7}{5} and y=-\frac{22}{5}.
