y+9=14 subtract 9 from each side to get y by itself y=5
Add (2 y - 1) to both sides to result in x - 1 = 2 y; divide by 2 to result in y = (x - 1)/2.
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.
That statement itself is an equation, and there are an infinite number of (x, y) pairs of numbers that satisfy it. To draw a graph of the equation, draw a straight line that rises toward the right at an angle of 45° and passes through [ y = -1/4 ] on the y-axis. The x-value and y-value of every point on that line satisfy your equation. (And we all know how many points there are on a line. Particularly on a line that has no ends.)
Sorry, but it is impossible to solve this equation by itself. Since you have two unknowns, you need two equation.

Nobody can help you find a solution until you get another equation to go along with this one. Your equation has two variables in it ... 'x' and 'y' ... so it has no unique solution all by itself.
Add (2 y - 1) to both sides to result in x - 1 = 2 y; divide by 2 to result in y = (x - 1)/2.
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
youranswer would be -23x+y=-253 because you add 23x to both sides (to y and itself)

Here is an example: 10x + 5y = 25 move the x's to the other side by subtracting them 5y = -10x + 25 divide the equation by 5(beacuse 5 is the number in front of y) to get y by itself y = -2x + 5
y = 3 in the equation 31 = 4 - 9y Solve for y. 31 - 4 = 4 - 9y - 4 Simplify 27 = 9y Divide both sides by 9 to get the term y by itself on one side of the equation. 27 / 9 = 9y / 9 Simplify 3 = y
