Answer 1

Answer:

7x-3y+15=0 - solution.

Step-by-step explanation:

Simplifying

7x + -3y + 15 = 0

Reorder the terms:

15 + 7x + -3y = 0

Solving

15 + 7x + -3y = 0

Solving for variable 'x'.

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

Add '-15' to each side of the equation.

15 + 7x + -15 + -3y = 0 + -15

Reorder the terms:

15 + -15 + 7x + -3y = 0 + -15

Combine like terms: 15 + -15 = 0

0 + 7x + -3y = 0 + -15

7x + -3y = 0 + -15

Combine like terms: 0 + -15 = -15

7x + -3y = -15

Add '3y' to each side of the equation.

7x + -3y + 3y = -15 + 3y

Combine like terms: -3y + 3y = 0

7x + 0 = -15 + 3y

7x = -15 + 3y

Divide each side by '7'.

x = -2.142857143 + 0.4285714286y
