The answer is concurrent validity.
This kind of validity is based on comparing the results with a measure that has been validated previously.
It is used in more subjective qualities given that they cannot be measured with instruments but it is more an appreciation that depends on the subject that performs the test.
Answer:
y = 7
x = 12
Step-by-step explanation:
14x+7y=217, then 14x = 217 - 7y
14x+3y=189, then 14x = 189 - 3y
217 - 7y = 189 - 3y
add 7y to each side of the equation:
4y + 189 = 217
subtract 1890 from each side:
4y = 28
divide both sides by 4:
y = 7
14x + 3(7) = 189
subtract 21 from each side:
14x = 168
divide both sides by 14:
x = 12
