If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.
Marat540 [252]

Answer:

-3

Step-by-step explanation:

Step 1: Write equation

-7.6(x - 1) = 7.3 - 7.4x

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

<u>Distribute -7.6:</u> -7.6x + 7.6 = 7.3 - 7.4x

<u>Add 7.6x on both sides:</u> 7.6 = 7.3 + 0.2x

<u>Subtract 7.3 on both sides:</u> 0.3 = 0.2x

<u>Divide both sides by 0.2:</u> x = 1.5

Step 3: Find <em>-2x</em>

-2(1.5) = -3
