8x+1=-x-1 4-5x=1+6x
8x+x=-1-1 -5x-6x=1-4

Answer:
[1] x - 6y = 3
[2] x + 2y = 5
Graphic Representation of the Equations :
-6y + x = 3 2y + x = 5
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -2y + 5
// Plug this in for variable x in equation [1]
[1] (-2y+5) - 6y = 3
[1] - 8y = -2
// Solve equation [1] for the variable y
[1] 8y = 2
[1] y = 1/4
// By now we know this much :
x = -2y+5
y = 1/4
// Use the y value to solve for x
x = -2(1/4)+5 = 9/2
Solution :
{x,y} = {9/2,1/4}

Answer:
1, 4, 9, 16, 25, etc
Step-by-step explanation:
a perfect square is a whole number multiplied by itself. it can be written with the notation ^2
to find a perfect square, simply square or bring to the 2nd power, any whole number
for example 9^2
this means that 9 is multiplied by ITSELF 2 times, it is NOT 9*2
it can also be written as 9*9=81
