Question

Will give medal to who ever answers first. Solve this problem using Elimination and Substitution, 7X-3X=20
5X+3Y=16
Please type it out.

Answer 1

Simplifying
7x = 3x + 20

Reorder the terms:
7x = 20 + 3x

Solving
7x = 20 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.
7x + -3x = 20 + 3x + -3x

Combine like terms: 7x + -3x = 4x
4x = 20 + 3x + -3x

Combine like terms: 3x + -3x = 0
4x = 20 + 0
4x = 20

Divide each side by '4'.
x = 5

Simplifying
x = 5

Answer 2

Simplifying
5x + 3y = 16

Solving
5x + 3y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.
5x + 3y + -3y = 16 + -3y

Combine like terms: 3y + -3y = 0
5x + 0 = 16 + -3y
5x = 16 + -3y

Divide each side by '5'.
x = 3.2 + -0.6y

Simplifying
x = 3.2 + -0.6y

Answer 3

The X coordinates should be 3 and the y should be 1/3.

Answer 4

what do you mean this isn't multiple choice is it

Answer 5

no

Answer 6

I have to solve the problems for the x and y values.
