Is the point (2,8) a solution of the equation y = 13x + 12?<br> O Yes<br> O No
vovikov84 [41]

Answer:

O No

Explanation:

Given equation: y = 13x + 12

To check if (2, 8) is a solution of the given equation.

Substitute x and y value in equation and check if it is true.

\rightarrow y = 13x+12

(x, y) = (2, 8)

\rightarrow 8 = 13(2)+12

simplify

\rightarrow 8 = 38

This following statement is false and hence (2, 8) is not a solution.

Can someone please help me I've been stuck on this for so long​
Vilka [71]

Answer:

x = -3, y=2

Step-by-step explanation:

x+3y =3

3y -2x =12

Solve the first equation for x

x = 3-3y

Substitute this into the second equation

3y -2(3-3y) =12

Distribute

3y -6 +6y =12

Combine like terms

9y -6 =12

Add 6 to each side

9y-6+6 =12+6

9y =18

Divide each side by 9

9y/9 =18/9

y = 2

Now find x

x = 3 -3y

x = 3-3(2)

x = 3-6

x = -3

y=0.5x-2x-11x-28
1. subtract like terms
2. add 28 on both sides
3. so on and so forth...
