I need a step by step explanation on how you solved the equation.

Ghella [55]

Answer: x=3 and y=−2

Step-by-step explanation:

x=−2y−1;4x−4y=20

Step: Solve x=−2y−1 for x:

Step: Substitute−2y−1 for x in 4x−4y=20:

4x−4y=20

4(−2y−1)−4y=20

−12y−4=20(Simplify both sides of the equation)

−12y−4+4=20+4(Add 4 to both sides)

−12y=24

−12y

−12

(Divide both sides by -12)

y=−2

Step: Substitute−2 for y x=−2y−1:

x=−2y−1

x=(−2)(−2)−1

x=3(Simplify both sides of the equation)

The sum of one-fifth of a number and two is five

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

Let us first write an equation where the unknown number is represented with variable x. The sum of a fifth of x and two is five:

$\frac{1}{5} x+2=5$

Great! Let's solve for x by isolating the variable.

$\frac{1}{5}x=3\\x=15$

Therefore, the unknown number is 15.

I hope this helps! Let me know if you have any questions :)
