Answer:

6 1/6 (i think )

substitute 4 in for a, -5 for b and -7 for c

(4+ 2 * - 7 * - 5)/3 * 4

3*4 = 12

4+2 * - 7 * - 5) / 12

-7 * - 5 = 35 (same sign so positive)

(4+ 2* 35)/12

2*35 = 70 and 70+4 = 74.

74/12 is what we have, and we can simplify this to 37/6 by dividing both the numerator and denominator by 2. now we convert to mixed fraction and get 6 1/6.

If three times a number minus 2 equals 13, what is the number?

Nana76 [90]

Change the messy words into numerals
3 times a number minus 2    equals    13
3 × n - 2 = 13

3n - 2 = 13
take 2 to the other side
3n - 2 + (2) = 13 + (2)
3n = 15

Divide by 3 on either sides to isolate n
$\frac{3n}{3}$ = $\frac{15}{3}$
3 and 3 cancels out

n = 5

check:
3 times 5 minus 2 equals 13
3   × 5 - 2 = 13
15 - 2 = 13
13 =    13

The number is 5
