If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4

The correct result would be x = - 7.

Firdavs [7]
X-4y=-12
4x-y=12

eliminate y's
multily 2nd equaiton by -4 and add to top one

x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60

-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4

x=4
y=4
