Solve the system of equations

Question

y=-3x-2

 

y=7x+3

Answer 1

(1)  y = -3x - 2

 

(2)  y = 7x + 3

 

equating (1) and (2):  7x + 3 = -3x - 2 ---> 10x = -5 ---> x = -5/10

 

                                ---> x = -1/2 ---> y = 7x + 3 = 7(-1/2) + 3

 

                                ---> y = -7/2 + 6/2 ---> y = -1/2
