Solve for X:
5(x−8)+21=0
To solve the linear equation 5(x−8)+21=0, follow these steps:
- Step 1: Distribute the 5 across (x−8).
The equation becomes:
5x−40+21=0.
- Step 2: Combine the constants on the left side.
Combine −40 and 21:
5x−40+21=0.
Convert −40 into a fraction to simplify: −40=−280.
The equation becomes:
5x−280+21=0.
Simplify it to:
5x−279=0.
To move −279 to the other side, we add 279 to both sides:
5x=279.
Divide both sides by 5 to isolate x:
x=279÷5.
x=279×51.
x=1079.
Therefore, the solution to the equation is x=1079.
