Solve for "y". Since "x" isn't specified, you can substitute any number for "x".

Simply substitute any value for y, solve for x for points along the line Y = 2X + 1

Nothing will solve an expression. You need an equation (an equality or an inequality) beofre a solution of any kind is possible. Tha means you need something on both sides of the equality (or inequality) sign.

x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5

Yes.

If you know that the associative property of addition means that the terms can be added in any order and that a number and its additive inverse equals zero, you can see that the terms cancel each other out and the whole thing equals zero, but I think that mental addition still qualifies as addition.

There are infinitely many ordered pairs that satisfy this equation. Supply any value for x, then solve for y to get the other part of the pair.

Answer by Hilmarz for a very similar question: When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations. Pricen2: given that there is no second equation with which to solve the original equation the values of x and y could be any of great number of values. If you knew the value of x then you would use y=3-x to find the value of y If you knew the vlaue of y then you would use x=3-y to find the value of x

Any number minus itself equals zero. Any number plus its opposite equals zero. Any number times zero equals zero.

well it equals 4 any way you put

You can't simplify this any further. y=-x is the equation of a line.

To solve the given terms is almost impossible in the absence of any plus, minus and equality signs.

The property is identity property of addition. This property states that any number plus 0 equals that number. identity property of multiplication states that any number times 1 equals that number.

Yes. That is true for any number "a".
