Answer 1

To determine who among Tamara, Payton, Krish, and Haruki is correct about the solution sets of the linear equations, we need to solve each equation.

Equation A: $3(4-5h)-7=-12+2h$

1. Distribute on the left: $$12-15h-7=-12+2h$$ Simplifying gives: $$5-15h=-12+2h$$

2. Add $15h$ and $12$ to both sides: $$5+12=15h+2h$$ $$17=17h$$

3. Solve for $h$: $$h=1$$

Equation B: $2(p-3)-1=6p+142$

1. Distributing on the left: $$2p-6-1=6p+142$$ Simplifying gives: $$2p-7=6p+142$$

2. Subtract $2p$ from both sides: $$-7=4p+142$$

3. Subtract 142 from both sides: $$-149=4p$$

4. Solve for $p$: $$p=-\frac{149}{4}$$

Equation C: $23v-3+83=-1$

1. Combine like terms on the left: $$23v+80=-1$$

2. Subtract 80 from both sides: $$23v=-81$$

3. Solve for $v$: $$v=-\frac{81}{23}$$

Summary of Solutions:

• Equation A: $h=1$
• Equation B: $p=-\frac{149}{4}$
• Equation C: $v=-\frac{81}{23}$

Evaluating Statements:

• Tamara: Claims A and C have the same solution. (Incorrect).
• Payton: Claims B and C have the same solution. (Incorrect).
• Krish: Claims A, B, and C all have the same solution. (Incorrect).
• Haruki: Claims that none of the equations have the same solution. (Correct).

Thus, the correct answer is Haruki.
