*Proportionality*. If you divide both sides of the equation by x, you’ll see why: k = y/x, or the *proportion* of y to x.

Solve this system of linear equations. separate the x- and y- values with a coma.

brilliants [131]

The solution is (2, -4).

We can solve this with the elimination method. Multiply the first equation by -2 and then add the two equations.

-20x + -12y = 8
20x + 10y = 0 Add the two equations

-2y = 8
y = -4

Now, just input -4 for y into either equation, you will get 2 for x.

Step-by-step explanation:

Step 1: Define equation

5x + 2 = 20

Step 2: Solve for x

Subtract 2 on both sides: 5x = 18
Divide 5 on both sides: x = 18/5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 5(18/5) + 2 = 20
Multiply: 18 + 2 = 20
Add: 20 = 20

Here we see that 20 does indeed equal 20.

∴ x = 18/5 is a solution to the equation.
