What is the solution to the system of equations?
y = 2x – 3.5
x – 2y = –14
y-2x = -3.5
-2y+x = -14 or x = 2y-14 Use this value of x to sub into first equation
y - 2(2y-14) = - 3.5
y - 4y + 28 = - 3.5
-3y = -31.5
y = 10.5 Substitute this value of y into one of th equations to find x
x = 2y-14
x = 2(10.5) -14
x = 7
y-2x = -3.5
-2y+x = -14 or x = 2y-14 Use this value of x to sub into first equation
y - 2(2y-14) = - 3.5
y - 4y + 28 = - 3.5
-3y = -31.5
y = 10.5 Substitute this value of y into one of th equations to find x
x = 2y-14
x = 2(10.5) -14
x = 7
