Solve

1) 3x - 10 = 5x + 22

2) log 5 - log 2x = 1

3) x^3+2x+3=0

i am awful at math and i have to solve a ton of equations like this, with steps ?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
