Add the coefficients of the variable term X. 2 + 3 + 8 = 13X
1,4,6,4,1
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
(x + 5)(x + 8)
1over3x+x+x+8+x=15
Literal coefficients are the non-numeric multipliers of expressions (or terms). In this case, they are x and y.
0
(X) x (4) x (8) x (12) = 384 X
x - 8 + x - 5 + x + 1 = 3x - 12
(x+1)(x+8)
It is x+9, provided that x is not -8.
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
