Question

x + 2y = 105
4x + 3y = 375
Find the value of x and y

Answer 1

Answer:

x=21, y=75

Step-by-step explanation:

4x+x=105, 2y + 3y= 375

5x=105, 5y = 375

x=105/5, y=375/5

x= 21, y= 75

Answer 2

Answer:

x+2y=105

4x+3y=375

By multiplying 4 to eq 1

4(x+2y)=4×105

4x+3y=375

4x+8y=420

4x+3y=375

By subtracting eq2 from eq1

5y=45

y=9

since,y=9

therefore, x= x+2y=105

x+2×9=105

x+18=105

x=105-18

x=87

therefore, x=87 and y=9
