Answer:
e = 9
Step-by-step explanation:
ok e is just x, so we have to get it alone
4e - 10 = 2e + 8
We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..
2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..
2e = 18
18/2 = 9
simple explanation
4e - 10 = 2e + 8
2e = 18
e = 9
(does that make sense)
Answer:
x = 2 - 5
, x = 2 + 5
Step-by-step explanation:
x² - 4x = 71
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = 71 + 4
(x - 2)² = 75 ( take the square root of both sides )
x - 2 = ± 
= ± 5 ( add 2 to both sides )
x = 2 ± 5
then
x = 2 - 5 , x = 2 + 5
Answer:
well technically it is -8x7 because it has the word times and most of the time times means multiplication
