Hi !
the answer is 5y+4
please let me know if im wrong (:
Answer:
To solve a system of linear equation graphically, it is best to write both equations in slope-intercept form first. After you put them in slope-intercept form, you should be able to graph them easily.For one solution, the two lines have to intersect at exactly one point, since both equations are satisfied at the intersection.
For no solution, the two lines have to never intersect, which means they have to be parallel lines. In other words, no solution will satisfy both equation.
I believe the decimial point divides between the dollar value and the cent value in american currecy. aka the decimial point symbolizes the cent value.
A>2.8
start at 2.8 on the number line, using the last symbol move it to the right

You have the following equation:
In order to solve the previous equation for y, proceed as follow:
3 + y/2 = -212 subtract 3 both sides
y/2 = -212 - 3 simplify right side
y/2 = -215 multiply by 2 both sides to cancel the denominator left side
y = -215(2)
y = -430
Hence, the solution for y in the given equation is y = -430
