3x2+14x+8 = 0 x = -2/3 or x = -4
(2, 1)

x=-1 ^ how do you know?
It is (-1, 3).
s = -2 -4r
To do it in steps... 10% of 185 is 18.5 20% is 18.5 x 2 which equals 37
you need 2 equations to solve for 2 variables
There are 2 unknowns
Solving by the elimination method: x = 7 and y = 2
-2=4r+s s=-4r-2 or s=-(4r+2)
Solving by elimination: p = 3 and q = -2
x = 2 or x = 2/5
12y = 8x + 24 so y = 2x/3 + 2
Solving the simultaneous equations works out as x = -2 and y = -2 So the lines intersect at: (-2, -2)
The equation 5X plus 4 X-2-2X 2 X-1 plus 3X plus 2 equals 2. This is a math problem learnt in college.
You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)
