Solve the system of linear equations by elimination -x+y=4;x+3y=4
mamaluj [8]

Answer:

the solution is (-8, 4)

Step-by-step explanation:

Let's use the addition/subtraction method here to eliminate one variable:

-x+y=4

x+3y=4

Combining these two equations results in

4y = 8, so that y = 2.  Substituting y = 2 into the second equation, we get:

x + 3(2) = 4, or x = -2.

Then the solution is (-8, 4)

5x - 2 = 10 - X<br> Please help
finlep [7]

Answer:

x = 2

Step-by-step explanation:

5x - 2 = 10 - x

<em>Add x to both sides</em>

6x - 2 = 10

<em>Add 2 to both sides</em>

6x = 12

<em>Divide both sides by 6</em>

x = 2
