Answer:

(-11)/5

Step-by-step explanation:

Simplify the following:

4/5 - 3

Put 4/5 - 3 over the common denominator 5. 4/5 - 3 = 4/5 + (5 (-3))/5:

4/5 + (5 (-3))/5

5 (-3) = -15:

4/5 + (-15)/5

4/5 - 15/5 = (4 - 15)/5:

(4 - 15)/5

4 - 15 = -(15 - 4):

(-(15 - 4))/5

| 1 | 5

- | | 4

| 1 | 1:

Answer:  (-11)/5

5-2(4a+1)+3a=13 <br><br> A= 2/3<br> A= -2<br> A= -6/5<br> A=2
VMariaS [17]

Answer:

                   a = -2

Simplifying 5 + -2(4a + 1) + 3a = 13 Reorder the terms: 5 + -2(1 + 4a) + 3a = 13 5 + (1 * -2 + 4a * -2) + 3a = 13 5 + (-2 + -8a) + 3a = 13 Combine like terms: 5 + -2 = 3 3 + -8a + 3a = 13 Combine like terms: -8a + 3a = -5a 3 + -5a = 13 Solving 3 + -5a = 13 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5a = 13 + -3 Combine like terms: 3 + -3 = 0 0 + -5a = 13 + -3 -5a = 13 + -3 Combine like terms: 13 + -3 = 10 -5a = 10 Divide each side by '-5'. a = -2
