rearrange 3x+y =-5 to solve for y:
y = -3x-5
substitute -3x-5 for y into the second equation:
12x + 3y = 13
12x + 3(-3x-5) = 13
12x - 9x - 15 = 13
3x = 28
x = 28/3
y = -3x-5 = -33
solution: (28/3, -33)

Hello,
Shall we begin?
x + 2 ( x + 2 ) = 16
x + 2x + 4 = 16
3x = 16 - 4
3x = 12
x = 12/3
x = 4
<span>Answers: x = 4</span>
I think it is the first one but I might be wrong
Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.
