Я не уверена что 2 правельно




Let's solve the equations step by step.
- Solve the first equation: (2x - 1) - (3x + 4) = 10
To solve this equation, we need to combine like terms and isolate the variable 'x' on one side of the equation.
Step 1: Distribute the negative sign through the second parentheses: (2x - 1) - 3x - 4 = 10
Step 2: Combine like terms: -1x - 5 = 10
Step 3: Move the constant term to the other side by adding 5 to both sides: -1x = 15
Step 4: Divide both sides by -1 to solve for 'x': x = -15
Now we have the value of 'x' from the first equation.
- Solve the second equation: |x| + 10 = 5
In this equation, we have an absolute value, so we need to consider both the positive and negative solutions for 'x'.
Step 1: Move the constant term to the other side by subtracting 10 from both sides: |x| = -5
Since the absolute value of any number is always non-negative (or zero), there is no real value for 'x' that can satisfy this equation. Therefore, the second equation has no real solutions.
In summary: The first equation has a solution: x = -15 The second equation has no real solutions.
