Answer:

u = 5/4

Step-by-step explanation:

<u>Step 1:  Distribute on the right side </u>

3 = 7(4 - 2u) - 6u

3 = (7 * 4) + (7 * -2u) - 6u

3 = 28 - 14u - 6u

<u>Step 2:  Combine like terms </u>

3 = 28 + (-14u - 6u)

3 = 28 + -20u

<u>Step 3:  Subtract 28 from both sides </u>

3 - 28 = 28 - 20u - 28

-25 = -20u

<u>Step 4:  Divide both sides by -20 </u>

-25 / -20 = -20u / -20

5/4 = u

Answer:  u = 5/4

Answer:

u = 5/4

Step-by-step explanation:

to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.

solution

3=7(4 - 2u)-6u

3 = 28- 14u - 6u

collect the like terms

3 + 14u + 6u = 28

20u = 28 - 3

20u = 25

divide both sides by the coefficient of u which is 20

20u/20 = 25/20

u = 5/4

Ber [7]
Given ---›

y = -3

&

y = x - 0.8

So,
=> x = y + 0.8

=> x = -3 + 0.8

=> x = -2.2

Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)

10 is 5% of what number
GarryVolchara [31]
We can use proportion to get the result
10 ----------- 5%
x ------------- 100%
Crossmultiply proportion

5*x=10*100
5x=1000     /:5 divide both sides by 5
x=1000:5
x=200 - its the answer
