<u>Solution: ======> x = -10</u>
<u>Long Version from Calculation 1</u>
<u>Equation</u>
1.4x + 6.1 = –7.9
<u>Steps:</u>
<u>Step 1): Multiply Both sides by 10:</u>
1.4x * 10 + 6.1 * 10 = –7.9 * 10
<u>Refine:</u>
14x + 61 = -79
<u>Step 2): Subtract 61 from both sides:</u>
14x + 61 - 61 = -79 - 61
<u>Simplify:</u>
14x = 140
<u>Divide both sides by 14:</u>
14x/14 = -140/14
Simplify:
14x/14 = x =====> 14x/4
<u>Divide the numbers:</u>
14/14 = 1
= x
-140/14 = -10
-140/14
<u>Apply the fraction Rule:</u>
-a/b = - a/b
= -140/14
<u>Divide the numbers:</u>
140/14 = 10
= -10
<u>Answer, Letter Choice, (A), x = -10</u>
<u>Short Version</u> <u>From Calculator Number 2:</u>
Equation: 1.4x + 6.1 = -79
<u>Solution Option (A), x = -10</u>
<u>Let's solve your equation step by step:</u>
1.4x + 6.1 = -7.9
<u>Step 1 Subtract 6.1 from both sides:</u>
1.4x + 6.1 - 6.1 = -7.9 - 6.1
1.4x = -14
<u>Step 2 Divide both sides by 1.4:</u>
1.4x/1.4 = -14/1.4
x = -10
<u>Answer x = -10 Option (A)</u>
Hope that helps!!!! : )
