solve equation 5w+7(3-4w)=0

-1 1/9

Get rid of parenthesis.

5w + 21 - 28w = 0

Combine like terms.

21 - 23w = 0

Add 23w to both sides.

21 = 23w

Divide both sides by 23.

w = 21/23

To solve the equation 5w + 7(3 - 4w) = 0, you can follow these steps:

Step 1: Distribute the 7 to the terms inside the parentheses.
5w + 7 * 3 - 7 * 4w = 0
5w + 21 - 28w = 0

Step 2: Combine like terms.
-23w + 21 = 0

Step 3: Move the constant term to the other side of the equation.
-23w = -21

Step 4: Divide both sides of the equation by -23 to isolate w.
w = (-21) / (-23)

Step 5: Simplify the fraction if possible.
w ≈ 0.913

So, the solution to the equation is w ≈ 0.913.
