Question

solve the following system of equations
x +5y = 7 (1)
x=3-5y (2)
i dont know how to do this becasue for ()s

Answer 1

that means equation 1 and equation 2

they are not in the real equation.

Answer 2

there are no solutions the lines are parallel

Answer 3

y=-1/5 x+7 and y=-1/5x+3 will not cross, therefore no solution exists, you can also see this if you subtract the equations, 0 = 4 doesn't work
