To solve the equation, you can follow these steps:
1. Distribute the -5 to both terms inside the parentheses:
20x - 5*6x - 5*15 = -45
20x - 30x - 75 = -45
2. Combine like terms on the left side of the equation:
-10x - 75 = -45
3. Add 75 to both sides of the equation to isolate the variable term:
-10x = -45 + 75
-10x = 30
4. Divide both sides of the equation by -10 to solve for x:
x = 30 / -10
x = -3
Therefore, the solution to the equation is x = -3.
Solve for x : 20x−5(6x+15)=−45 .
