1. Y = 35 X= 6 Explanation: the pattern at x is adding 1 to the numbers and the pattern at y is multiples of 7 2. X= 7 Y= 1 Explanation: the pattern for both y and x is adding one to each of the numbers. 3. X= 1 Y=2 Explanation: the pattern for x is subtracting 4 from each of the numbers and for y you will have to subtract 2 from each number. 4. X= 12 Y= 15 Explanation: the pattern at both y and x is adding on one to each of the numbers .
Any value you choose for x will make the equation a TRUE statement. This type of equation is called an identity, and the solution set is all real numbers.
