-5y=-5
7x+6y= 7
Is (5,1) a solution of the system?

No, (5,1) is not a solution of the system. (1/7,-1) is the solution of the system.

Step-by-step explanation:

Step1:

-5y= -5

divide -5 on both sides

y= 1

Step 2:

7x+6(1)=7

7x+6=7

   -6  -6

7x = 1

divide 7 on both sides

x = 1/7

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the answer is 489
