Let's break down the problem step by step to find the coefficients of the specified terms in the given expressions.

### Expression 1: $$ -3x^{2} + 4x - 3 $$

1. **Identify the term in $$ x $$**:
   - The term in $$ x $$ is $$ 4x $$.
   
2. **Coefficient of the term in $$ x $$**:
   - The coefficient is $$ 4 $$.

### Expression 2: $$ (a+b)x^{3} - x^{2}y + x - 1 $$

1. **Identify the term in $$ x^{2} $$**:
   - The term in $$ x^{2} $$ is $$ -x^{2}y $$.
   
2. **Coefficient of the term in $$ x^{2} $$**:
   - The coefficient is $$ -y $$.

3. **Identify the term in $$ x^{3} $$**:
   - The term in $$ x^{3} $$ is $$ (a+b)x^{3} $$.
   
4. **Coefficient of the term in $$ x^{3} $$**:
   - The coefficient is $$ a + b $$.

### Summary of Coefficients:
1. Coefficient of $$ x $$ in $$ -3x^{2} + 4x - 3 $$ is $$ 4 $$.
2. Coefficient of $$ x^{2} $$ in $$ (a+b)x^{3} - x^{2}y + x - 1 $$ is $$ -y $$.
3. Coefficient of $$ x^{3} $$ in $$ (a+b)x^{3} - x^{2}y + x - 1 $$ is $$ a + b $$.
- Coefficient of $$ x $$ in $$ -3x^{2} + 4x - 3 $$ is $$ 4 $$. - Coefficient of $$ x^{2} $$ in $$ (a+b)x^{3} - x^{2}y + x - 1 $$ is $$ -y $$. - Coefficient of $$ x^{3} $$ in $$ (a+b)x^{3} - x^{2}y + x - 1 $$ is $$ a + b $$.

(10) \( 7-2 m x n \) State the coefficient of the term indicated: (1) \( -3 x^{2}+4 x-3 \) (2) \( -3 x^{2}+4 x-3 \) (the term in \( x \) ) (2) \( (a+b) x^{3}-x^{2} y+x-1 \) (the term in \( x^{2} \) ) (the term in \( x^{3}, x^{2} \)
