-13=3(x+2)-10
-13=3(x+2)-10
-13 = 3x + 6 - 10
-13 + 4 = 3x
-9 = 3x
-3 = x
To solve the equation -13 = 3(x + 2) - 10, we can follow these steps:
Step 1: Distribute the 3 to the terms inside the parentheses:
-13 = 3x + 6 - 10
Step 2: Combine like terms:
-13 = 3x - 4
Step 3: Isolate the variable term by subtracting -4 from both sides of the equation:
-13 + 4 = 3x
Simplifying further:
-9 = 3x
Step 4: Solve for x by dividing both sides of the equation by 3:
-9/3 = x
Simplifying:
-3 = x
Therefore, the solution to the equation -13 = 3(x + 2) - 10 is x = -3.
