If there is one equation that can be solved, then (x-2)2 + (y-3)2 = 0
For an equation such as x+y-5 = 0 you will have an infinity of solutions unless you add another, independent equation and solve them simultaneously.
y = - 1/3 x + any number.
The expression is (2x-3)(3x-2) which equals 6x2 -13x +6

Rearranging the original equation, we get y=-(2/3)x+12. Since 12 is the constant, this is the point that the line of this equation will cut the y-axis if x=0. Therefore, -(2/3) is the gradient and for an equation to produce a parallel line, the gradient must be equal. Summing up, y=-(2/3)+c (where c equals any real number) would be parallel

Points: (3, 2) and (-9, 6) Slope: -1/3 Equation: 3y = -x+9
y = - 1/3 x + any number.
Y+2 = 2 (x-3)
Points: (6, -3) and (-4, -9) Slope: 3/5 Equation: 5y = 3x-33

2 represents two molecules of silver nitrate. 3 represents the number of oxygen atoms in each molecule of silver nitrate [or the number of oxygen atoms in the nitrate ion].
y = 0x + 3 or just y = 3
The chemical equation for the reaction between aluminum and sulfur is: 2 Al + 3 S -> Al2S3 This equation represents aluminum reacting with sulfur to form aluminum sulfide.
If the number is N, then 3 more is N+3, set equal to 7: N+3=7
Statement 3 does NOT describe a chemical equation. It should read: "The arrow represents the direction in which the reaction is proceeding."
The expression is (2x-3)(3x-2) which equals 6x2 -13x +6
