Solve they system by addition 7x-2y=3 4x+5y=3.25
noname [10]

Answer: x = 2/7y + 3/7 and

x= -5/4y + 0.8125

Step-by-step explanation: Let's solve for x.

7x−2y=3

Step 1: Add 2y to both sides.

7x − 2y + 2y= 3 + 2y

7x = 2y + 3

Step 2: Divide both sides by 7.

7x/7 = 2y+3/7    this is for the second answer                                                  Step 1: Add -5y to both sides.

4x+5y+−5y=3.25+−5y

4x=−5y+3.25

Step 2: Divide both sides by

4/4 x 4 = −5y + 3.25/4
