Solve the system of linear equations by graphing
y = -5/2× -7
X + 2y = 4

Step-by-step explanation:

hello :

y = -5/2× -7 (*)

X + 2y = 4...(**)

by (*) put the value of y in (**) : x+2(-5/2× -7 ) =4

x -5x -14 = 4

-4x-14 = 4

-4x =18

x = -18/4 = -9/2

but  :  y = -5/2× -7  so : y = -5/2(-9/2) -7=45/4 -7...continu

a) 7x=7
