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