Question

Let f(x)=5x-6 and g(x)=7x-2. find f(x)+g(x) eeek how do i solve this?

Answer 1

f(x) = 5x-6 ----(1)
g(x)=7x-2 ----(2)

(1) +(2)
f(x) + g(x) = 5x -6 + 7x -2..

can u continue ?

Answer 2

courage @memirobb !

Answer 3

just assum the same terms

Answer 4

u can add and subtract the like terms...
i mean the terms which include "x"
for an example
if there is something like this
8x + 3x
u can add 8 and 3 together and write 11x
if there is
8x - 3x
u can sub 3 from 8 and write the answer as 5x
in ur question if u bring up the like terms close together
f(x) + g(x) = 5x -6 + 7x -2.
write the terms with same variable close
= 5x + 7x -6 - 2
now its like adding
8x and 3x like i mention above... u can do the same and simplify 5x + 7x..
-6 -2 ... i think u dont have a problem simplifying that part

Answer 5

@memirobb what is the problem ?

are you here again ?

Answer 6
