*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.

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

5x + 2 = 20

<u>Step 2: Solve for </u><em><u>x</u></em>

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

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    5(18/5) + 2 = 20
  2. Multiply:                               18 + 2 = 20
  3. Add:                                     20 = 20

Here we see that 20 does indeed equal 20.

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