Question

I need help finding the errors in these problems! (Problem attached)

Answer 1

in step 2 when you have subtituted the value of x= -5y /4

so there you have missed the y

check it please !

Answer 2

step 3 depend to the step 2

so because step 2 not is right so this mean that step 3 not is right the same

ok ?

Answer 3

what is it once you fix it though?

Answer 4

in case of

10x +10y = -5 so you can factorizing out on the left side 5

5(2x +2y)= -5 than now divide both sides by 5 and will get

2x +2y = -1

do you can continue it now ?

Answer 5

Awesome thanks yeah
