Answer:

0 = 0

Step-by-step explanation:

2(x+4) = 4x + 3 - 2x + 5

Distribute

2(x+4) = 4x + 3 - 2x + 5

2x + 8 = 4x + 3 - 2x + 5

Add the numbers

2x + 8 = 4x + 3 - 2x + 5

2x + 8 = 4x + 8 - 2x

Combine like trems

2x + 8 = 4x + 8 - 2x

2x + 8 = 2x + 8

Subtract 8 from both sides of the equation

2x + 8 = 2x + 8

2x + 8 - 8 = 2x + 8 - 8

Simplify

Subtract the numbers

2x = 2x

Subtract 2x from both sides of the equation

2x = 2x

2x - 2x = 2x - 2x

Simplify

Combine like terms

0=0

Result

0 = 0

The input is identity: it is true for all values.

If 21 is added to a number the result is 40 less than twice the number what is the number?
Karolina [17]
If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)

x + 21 = 2x - 40   Add 40 to both sides
x + 61 = 2x           Subtract x from both sides
      61 = x             Switch the sides to make it easier to read
       x = 61

What factors multiply to -80 and add to 6
forsale [732]

80 = -1(80), -2(40), -4(20), -5(4),

Total answers include: -81, 79, -42, 16, -9, and 1.

None of them add up to 6!

Are you doing polynomial equations?

If so, you can solve it the hard way.

x^2 + 6x -80 = 0

(x^2 + 6x + 9) - 80 = 9

(x+3)^2 = 89

(x+3) = 9.43

x = 6.43

If you're not doing those then I'm afraid your question has no answer.

Hope that helps!
