Question

Solve for x and y 2x+3y=7 and 3x_5y =1

Answer 1

Answer:

Step-by-step explanation:

2x+3y=7 ( equation 1)

3x-5y=1 (equation 2)

Multiply eq1 by 3 and eq2 by 2 and subtracting

6x+9y=21 (eq3)

6x-10y=2 (eq4)

Sign change eq4

-6x+10y=-2 (eq5)

Now subtracting eq 3 and eq 5

6x+9y=21

-6x+10y=-2

___________

19y=19

Y=19/19

Y=1

Putting the value of y in eq1

2x+3(1)=7

2x+3=7

2x=7-3

2x=4

X=4/2

X=2

X=2,y=1
