Question

solve for c.
1.4(-4 + c) - 10.9 = 3.1
c = \boxed{}

Explanation:

Step1: Add 10.9 to both sides

$1.4(-4 + c) - 10.9 + 10.9 = 3.1 + 10.9$
Simplify: $1.4(-4 + c) = 14$

Step2: Divide both sides by 1.4

$\frac{1.4(-4 + c)}{1.4} = \frac{14}{1.4}$
Simplify: $-4 + c = 10$

Step3: Add 4 to both sides

$-4 + c + 4 = 10 + 4$
Simplify: $c = 14$

Answer:

14
