Answer:

(1,3)

y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3
