2x+y=-2 x+y=5 The x-coordinate of the solution to the system shown is __ 7 -3 3 -7

To solve the system of equations, we can use the substitution method. From the second equation, we can express y in terms of x:y = 5 - xNow, substitute this expression for y into the first equation:2x + (5 - x) = -2Simplify the equation:2x + 5 - x = -2x + 5 = -2x = -7So, the x-coordinate of the solution to the system is -7.
