To determine who is correct about the solution sets of the equations, we need to solve each equation and see if they have the same solutions.
Equation A: \[ 3(4−5h)−7=−12+2h \]
-
Distribute on the left side: \[ 12 - 15h - 7 = -12 + 2h \] \[ 5 - 15h = -12 + 2h \]
-
Add \(15h\) to both sides: \[ 5 = -12 + 17h \]
-
Add \(12\) to both sides: \[ 17 = 17h \]
-
Divide by \(17\): \[ h = 1 \]
Equation B: \[ 2(p−3)−1=6p+142 \]
-
Distribute on the left side: \[ 2p - 6 - 1 = 6p + 142 \] \[ 2p - 7 = 6p + 142 \]
-
Subtract \(2p\) from both sides: \[ -7 = 4p + 142 \]
-
Subtract \(142\) from both sides: \[ -149 = 4p \]
-
Divide by \(4\): \[ p = -\frac{149}{4} \]
Equation C: \[ 23v−3+83=−1 \]
-
Combine the constants on the left side: \[ 23v + 80 = -1 \]
-
Subtract \(80\) from both sides: \[ 23v = -81 \]
-
Divide by \(23\): \[ v = -\frac{81}{23} \]
Now that we have the values:
- From Equation A, we have \(h = 1\).
- From Equation B, we have \(p = -\frac{149}{4}\).
- From Equation C, we have \(v = -\frac{81}{23}\).
Now, we analyze the statements:
- Tamara states that Equation A and Equation C have the same solution. (False, \(h \neq v\))
- Payton states that Equation B and Equation C have the same solution. (False, \(p \neq v\))
- Krish states that all three have the same solution. (False)
- Haruki states that none of the equations have the same solution. (True)
Thus, the only correct statement is Haruki.
