Solve the system of equations by substitution. What is the solution for x? (1 point) 2x + y = 1
4x + 2y = −1

                2x + y = 1

         2x - 2x + y = 1 - 2x

                        y = 1 - 2x

                        y = -2x + 1

              4x + 2y = -1

   4x + 2(-2x + 1) = -1

4x + 2(-2x) + 2(1) = -1

         4x - 4x + 2 = -1

                        2 ≠ -1

The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
