One fifth of a number plus three times the number is equal to 42 Moré than twice the number. Whats the number

35

Step-by-step explanation:

Let number = x

(1/5 of x) + (3 * x) = 42 + (2 * x)

x/5 + 3x = 42 + 2x

1/5x + 3x - 2x = 42

1 1/5x = 42

6/5 x = 42

x = 42 ÷ 6/5

x = 42 * 5/6

x = 210 / 6

x = 35

The number is 35

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
