What is the answer to this problem
x + 2y = 3
3x - 2y = 5 using subsitoution

x=2

y=1/2

Step-by-step explanation:

x + 2y = 3 Equation 1

3x - 2y = 5 Equation 2

From equation 1, we make x the subject

x + 2y = 3

x=3-2y Equation 3

We substitute x for 3-2y in equation 2 to get y

3x - 2y = 5

3(3-2y)-2y=5

9-6y-2y=5

9-8y=5

9-5=8y

4=8y

Divide both sides by 8

4/8=8y/8

4/8=y

y=1/2

Substitute y for 1/2 in equation 3

x=3-2y

x=3-2(1/2)

x=3-1

x=2

Let's use equation 2 to check if we are correct, note that both sides of the equation must be the same. We substitute x with 2 and y with 1/2

3x - 2y = 5

3(2)-2(1/2)=5

6-1=5

5=5

what are you trying to solve here

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
