Question

Solve for d.
-6.34 = 3.1(d+ 3.8) + -2.62

Answer 1

d = -5

Explanation:

-6.34 = 3.1(d+ 3.8) + -2.62

3.1(d+3.8)+(-2.62) = -6.34 [Add 2.62 to -6.34]

3.1(d+3.8) =-3.72 [Multiply 3.1 to (d +3.8)]

3.1d+11.78 = -3.72 [Add -11.78 to -3.72]

3.1d = -15.5 [Divide both side by 3.1]

d = -5

Answer 2

d = -5

Explanation:

-6.34 = 3.1(d+ 3.8) + -2.62

To solve for d, we can follow these steps:

Add 2.62 to both sides of the equation to isolate the term with d:

-6.34 + 2.62 = 3.1(d + 3.8)

-3.72 = 3.1(d + 3.8)

Divide both sides by 3.1 to isolate d:

`\sf (-3.72 )/( 3.1 )= d + 3.8`

-1.2 = d + 3.8

Subtract 3.8 from both sides to solve for d:

-1.2 - 3.8 = d

d = -5

Therefore, the solution to the equation is d = - 5.
