What is the solution for y=2x-1 and 5x-4y=1

one solution : ( 1 , 1)

Step-by-step explanation:

hello :

y=2x-1 (*)

5x-4y=1...(**)

put the value of y  by (*) in (**) : 5x-4(2x-1)=1

5x-8x+4 = 1

-3x = -3

x = 1

but y = 2x-1

so : y = 2(1)-1 =1

one solution : (1 , 1)

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
