Show me how to solve: x-{-9/14}=5/7

X-{-9/14}=5/7

X+9/14=5/7

Move +9/14 to the other side

Sign changes from +9'14 to -9/14

X+9/14-9/14=5/7-9/14

X=5/7-9/14

Find the common denominator for 5/7 which is 14

Multiply by 2 for 5/7

5(2)/7(2)=10/14

X=10/14-9/14

X=1/14

d? maybe

step-by-step explanation:

(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
