X = 135 and y = 15 Solved by addition and substitution
56
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
Not until it equals something. Equations have equals signs.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
28+28=56
You need two equations to use the addition method.
the answer
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.
X = 135 and y = 15 Solved by addition and substitution
1+23-4+56+7+8+9=100
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.
93-56 equals = 37
62-56 equals = 6
56-43.789 equals = 12.210999999999999
To find the number that, when multiplied by 3, equals 56, you would divide 56 by 3. So, 56 divided by 3 equals 18.6666667. Therefore, 18.6666667 times 3 equals 56.
They can but don't have to.
