-7x-2y= -13
x-2y= 11

Solve the question with substitution and show work

x=3,y= -4

Step-by-step explanation:

ii) x-2y=11

x=11+2y(i)

Now,

i) -7x-2y= -13

or, -7(11+2y)-2y= -13

or, -77-14y-2y = -13

or -14y-2y = -13+77

or -16y = 64

or y =64÷(-16)

:: y = -4

Again,

(ii) x-2y= 11

or x-2(-4)= 11

or x+8 = 11

or x = 11-8

:: x = 3

its kind of blurry. can you put a clearer pic?
