2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
(1, 1)
Factored, that's 4(5x + 1)(5x + 1) or 4(5x + 1)2 If the whole thing equals zero, x = -1/5
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
-5x + 1 = -10 -5x = -11x = 11/5 = 2 1/5

2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
Factored, that's 4(5x + 1)(5x + 1) or 4(5x + 1)2 If the whole thing equals zero, x = -1/5
5x+1+x-2 = 8x+6 5x+x-8x = 6+2-1 -2x = 7 x = -3.5
x = -2
Y=-1/2(x)
(3, 2)
3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1
8x-7 plus 2x equals 6 plus 5x plus 2?
x = 2, y = 1
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
