It is: (5x-1)(5x+1) = 0 when factored

Yes.

Multiply the bottom equation by -1

5x - y + 1 = 0

X = 1

If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.

(1, 1)

5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5

Factored, that's 4(5x + 1)(5x + 1) or 4(5x + 1)2 If the whole thing equals zero, x = -1/5

swop sides: 10 = 5x - 1 ie 11 = 5x so x = 2.2

y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7

Identity property. Anything multiplied by 1 will give an answer identical to the operand.

5x+1

x=1/5

5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5

5x=11y

-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11

45-5x = 5x+55 -5x-5x = 55-45 -10x = 10 x = -1

-30

4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6

If: 5x+1 = 21 Then: 5x = 21-1 => 5x = 20 Divide both sides by 5 and so x = 4

you would first do 10+5x-5=0, then 5x+5=0 and is factored by 5(x+1)=0. or if you want to know what x equals with, x=-1

If: 1/3-1/5x = 15 then x work out as -3/220

7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

The slope is ' 5 ', so both lines MUST be parallel.
