What is the solution to y = 2x + 3 for the replacement set x = {1.3}?

Answers

Answer 1

Answer: Simple. Substitue "1.3" for x in the given equation y = 2x + 3.

2x + 3 = y
2 * 1.3 + 3 = y
2.6 + 3 = y
5.6 = y

The solution to the equation with the replacement set {1.3} for x is {5.6} = y.
I hope you understand how to solve the equation! :)

Solve this system of linear equations. Separatethe x- and y-values with a comma.
20x + 11y = 37
4x + 3y = 13
Enter the correct answer.

Answers

Answer: x= -2 and y=7

Step-by-step explanation:

4×20x+11y=37

20×4x+3y=13

Using elimination method

80x+44y=148

80x+60y=260

-16y/-16=-112/-16

Y=7

Substitute for Y in equation (1)

20x+ 11(7)=37

20x+77=37

20x=37-77

20x/20= -40/20

X= -2

therefore, x=-2 and y=7
