3x+11=-4
please help idk what to do???
subtract 11 from both sides
3 x = -15
x = -5
3x+11=-4
Subtract 11 from both sides.
3x + 11 - 11 = -4 - 11
3x = -15
x = -15/3
x = -5
To solve the equation 3x + 11 = -4, we need to isolate the variable x. Here's how you can solve it step by step:
Step 1: Eliminate the constant term on one side. In this case, subtract 11 from both sides of the equation:
3x + 11 - 11 = -4 - 11
This simplifies to:
3x = -15
Step 2: Next, isolate x by dividing both sides of the equation by the coefficient of x, which is 3:
3x/3 = -15/3
This simplifies to:
x = -5
So, the solution to the equation 3x + 11 = -4 is x = -5.
