Problem 1: two numbers add together equals 47. their difference is 13. write and solve a system to find the two numbersproblem 2: the sum of two numbers is 54 and their difference is 12. write and solve a system to find the two numbers

34+13= 47

Step-by-step explanation:

47-34=13

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
