You mean -2x+5y=20 if it was that's how you do it
so if you're finding the x intercept the y will turn to 0 why because you're only looking for x their's no need for y
so it will be -2x+0=20
-2x=20 if it's multiplication then you change it to division
-2x/-2=20/-2
x=-10

Step-by-step explanation:
Let 
be the number of hours that the plan A last, an 
the number of hours of plan B. Then for the Wednesday you have:
And for the Thursday is:
Multiply the equation of Wednesday by -3:
Using the method of addition using this last equation and the equation of Thursday
Replacing the value of in one of the equations
Answer:
The first step should be adding 14 to both sides of the equation.
Step-by-step explanation:
14 must be added on both sides of the equation to get 13y by itself. The ultimate goal is to get y by itself if we are solving for y.
Once 14 is added on both sides, you'll get:
13y = 56.
Then 13 would be divided from both sides.
y = 4.3
