How do you solve x plus y equals 8 and 2x minus y equals 5 using the addition method?
If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
Is 3x 5 an equation?
Not until it equals something. Equations have equals signs.
How many solutions does this system of equations have 2x-3y equals -14 4x-6y equals -28?
The equations are identical in value, ie the second is merely twice the first...

What is 6a - 5b equals 9 using addition method?
You need two equations to use the addition method.
How do you Solve this system of equations using the addition method 6a - 5b equals 9 2a plus 5b equals 23?
the answer
Solve this system of equations using the addition method x plus y equals 6?
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.

Is addition and subtraction examples of equations?
Addition and subtraction are mathematical processes. They can be used in equations, which are statements that the values of two mathematical expressions are equal, but they are not equations by themselves.
