Answer:

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
