Solve. 3d-e=7 d+e=5 use the linear combination method. a. there is no solution. b. there are infinitely many solutions. c. the solution is (2,-1) d. the solution is (3,2)

the right answer is D) The solution is (3,2)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
