Question

2(5−d)=2−4d what's d?

Answer 1

2(5−d)=2−4d

10-2d=2-4d

10-2=-2d

8=-2d

d=-4

Hope this will help you.........

Answer 2

Answer:

hope it helps you:-)

Step-by-step explanation:

Step by step solution :

Step 1 :

Equation at the end of step 1 :

2 • (5 - d) - (2 - 4d) = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

2d + 8 = 2 • (d + 4)

Equation at the end of step 3 :

2 • (d + 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : d+4 = 0

Subtract 4 from both sides of the equation :

d = -4

One solution was found :

d = -4
