If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.
2 answers:
Answer:
3
Step-by-step explanation:
-7.6x+7.6=7.3-7.4x
-7.6x+7.4x=7.3-7.6
-0.2x=-0.3
X=-0.3/-0.2
X=3/2
2x. means multiply the ans you get for x by 2
2(3/2)
=3
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
