Question

Find the solution to the system of equations using substitution or elimination method

-2x+y=1
-2x+y =-3

Answer 1

The equations are parallel line and will have no solution

how to solve the equation

The given equation are

-2x + y = 1

-2x + y = -3

In -2x + y = 1, make y the subject of formula

y = 1 + 2x

plug in y

-2x + (1 + 2x) = -3

1 = -3

No solution
