multiply first equation by -2 and add to 2nd equation
-4x-6y=4
<u>4x+7y=-6 +</u>
0x+1y=-2
y=-2
sub back
2x+3y=-2
2x+3(-2)=-2
2x-6=-2
2x=4

Answer:
Mean: 49
Median: 48
Step-by-step explanation:
The mean is the total of all the values by adding them all together, then divided by the number of values.
The median is the middle number in the order of lowest to highest.
The two equations are equal. 3(3t-2) once distributed equals 9t-6 which the question says equals the equation on the left, 9t-6.
-2 - 1 = -3
The answer is -3.
