Question

can someone help me or tell me what I am doing wrong please
x=-2
-8x=10y+40


-8*2=10y+40
16=10y+40
how do I solve it from here?

Answer 1

should be -8 * (-2)...not 2

Answer 2

it should b -8*-2 as above it is x=-2

Answer 3

right that was a typo...then what? do I subtract 16 from 40 or 40 from 16 and divide? confused

Answer 4

-8*(-2)=10y+40
16=10y+40
10y=16-40
10y=-24
y=-2.4

Answer 5

how did you get -2.4

Answer 6

divide by 10 on both sides...I got it..thank you again...
