You can
put this solution on YOUR website!
distributing the -2 and the -4 ___ 1 - 2e + 2 = -3 - 12 + 20
consolidating terms ___ -2e + 3 = 5
subtracting 3 ___ -2e = 2
dividing by -2 ___ e = -1
sorry , no 7...

Nope.
If you replace
with 7, you get:
Clear the parentheses:
Do the multiplications:
Clear the parentheses:
Do the addition:
So, start again:
Calculate the value of the RHS. It is the same value we obtained doing the work already illustrated, namely 5:
Add -1 to both sides:
Divide both sides by -2:
Add 1 to both sides
