5x-2y = 4
2(3x+y = 9)
Multiply all terms in the second equation by 2:
5x-2y = 4
6x+2y = 18
Add the equations together:
11x = 22
Divide both sides by 11 to find the value of x:
x = 2
Substitute the value of x into the original equations to find the value of y:
Therefore: x = 2 and y = 3

What is 6a - 5b equals 9 using addition method?
You need two equations to use the addition method.
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.
How do I solve whole number equations that contain addition or subtraction?
The answer depends on the equation: there is no single method which can be used for all equations.
The addition method for x plus y equals 8 and -x plus 2y equals 7?
Add the two equations: x + y - x + 2y = 8 + 7 ie 3y = 15 so y = 5 making x = 3.
Solve this equation using addition method x plus y equals 8 and -x plus 2y equals 7?
The idea here is to add everything to the left side of both equations together, and everything on the right side. So, you get: x + y + 8 - x = 8 + 7 After simplifying, in this case you eliminate one variable, which is the purpose of this method. After solving for this variable, you can replace its value in any of the original equations to get the other variable.

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
Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
