Answer :

Space

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

2.50x + 15.00 = 1.00x

Step 2: Solve for x

  1. Subtract 1.00x on both sides: 1.50x + 15.00 = 0
  2. Subtract 15.00 on both sides: 1.50x = -15.00
  3. Divide both sides by 1.50: x = -10

Step 3: Check

Plug in x to verify it's a solution.

2.50(-10) + 15.00 = 1.00(-10)

-25 + 15.00 = -10

-10 = -10

Answer:

x = -10

Step-by-step explanation:

multiply both sides by 10:

2.50x*10+15*10=1.00x*10

Refine:

25x + 150 = 10x

Subtract 150 from both sides:

25x + 150 - 150 = 10x - 150

Simplify:

25x = 10x - 150

Subtract 10x from both sides:

25x - 10x = 10x - 150 - 10x

Simplify:

15x = -150

Divide both sides by 15:

15x/15 = -150/15

Simplify:

x = -10
