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.
