Solve the following equation for all values of x <br> 2x^2+18x-17=11x-2
Cerrena [4.2K]

2x^2 + 18x - 17 = 11x - 2

           -11x   +2    -11x   +2

2x^2 +7x - 15 = 0

(x - 1.5) (x + 5)

x = 1.5    x = -5

It looks a little less than 1/2 or 4/8, so probably 3/8 of the gas is left.

Elimination: 

3x - 9y = 3
6x - 3y = -24

3x - 9y = 3
18x - 9y = -72
(subtract)
-15x = 75
÷ -15
x = -5

(3 × -5) - 9y = 3
-15 - 9y = 3
+ 15
-9y = 18
÷ -9
y = -2

Substitution:

6x - 3y = -24
+ 3y
6x = -24 + 3y

÷ 6
x = 4 + 0.5y

3(4 + 0.5y) - 9y = 3
12 + 1.5y - 9y = 3
12 - 7.5y = 3
- 12
-7.5y = -9
÷ -7.5
y = 1.2

x = 4 + (0.5 × 1.2)
x = 4 + 0.6
x = 4.6

So this one didn't fail as much, but I got different numbers. If you have to give in values, I'd give in the values from the elimination because I don't trust myself when it comes to the substitution
