i keep gettin a decimal or a zero on this problem

-3(3x+15)-(10+X)=35

PLEASE HELP

-3(3x+15)-(10+X)=35

-9x -45 -10 - x = 35
-10x = 35 + 55
x = 90/-10
x = -9

-3(3x+15)-(10+X)=35

-9x - 45 - 10 - x = 35
-10x - 55 = 35
-10x = 90
x = -9

ty

To solve the equation: -3(3x+15)-(10+X)=35

Step 1: Distribute the -3 to the terms inside the parentheses:
-9x - 45 - (10 + x) = 35

Step 2: Simplify the expression inside the parentheses:
-9x - 45 - 10 - x = 35

Step 3: Combine like terms on the left side of the equation:
-10x - 55 = 35

Step 4: Move the constant term (-55) to the right side by adding 55 to both sides of the equation:
-10x = 35 + 55

Step 5: Simplify:
-10x = 90

Step 6: Divide both sides of the equation by -10 to solve for x:
x = 90 / -10

Step 7: Simplify the expression:
x = -9

Therefore, the solution to the equation is x = -9.
