Answer 2

OK to your question :

Answer 3

you see we have 2 equations here namely

\[2d+e=8 \]

Answer 4

\[d-e=4\]

Answer 5

we can see that adding the two equations will help us remove the e variable and help u get an equation containing only d which we can easily solve .

Answer 6

@peachykeene can u try that and report value for d ?
