Solve each equation for the given variable using your best guess and check skills after checking your guess by plugging it in to the equation, modify your guess if needed until you make a true statement and equality. REAL ANSWERS ONLY

Step-by-step explanation:

1)

4n+1=17

4n=16

n=4

2)

17=3x+2

3x=15

x=5

3)

5y-10=40

5y=50

y=10

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
