What is the the solution?
5x + 5y = 7
3x + 2y = 0

1. Let's solve for x.

5x+5y=7

Step 1: Add -5y to both sides.

5x+5y+−5y=7+−5y

5x=−5y+7

Step 2: Divide both sides by 5.

5x

5

=

−5y+7

5

x=−y+

7

5

x=−y+7/5

2. Let's solve for x.

3x+2y=0

Step 1: Add -2y to both sides.

3x+2y+−2y=0+−2y

3x=−2y

Step 2: Divide both sides by 3.

3x

3

=

−2y

3

x=−2/3y

Step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
