What is the answer to 3(x+1) = 5+x
AleksandrR [38]

3 (x + 1) = 5 + x

First you must distribute the 3 to the values inside the parentheses:

3 (x + 1) = 5 + x

(3 * x) + (3 * 1) = 5 + x

3x + 3 = 5 + x

Now you must combine like terms. Like terms are numbers that have matching variables like 3x and x OR are numbers with out variables like 3 and 5.

3x - x = 5 - 3

2x = 2

Next, to completely isolate x, divide 2 to both sides. Since 2 is being multiplied by x, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

2x / 2 = 2 / 2

1x = 1

Check:

3 (1 + 1) = 5 + 1

3 (2) = 5 + 1

6 = 6

^^^This is true, therefore:

x = 1

Hope this helped!

When 5x2+2=4x is solved using the quadratic formula, what are the values of a,b, and c?
viktelen [127]

Hey there,

<u>What </u><u>are </u><u>the </u><u>values </u><u>of </u><u>a,</u><u> </u><u>b </u><u>and </u><u>c?</u>

5x² + 2 = 4x

5x² + 2 - 4x = 4x - 4x

5x² - 4x+ 2 = 0

<em>Quadratic </em><em>général </em><em>e</em><em>quation</em><em>:</em>

ax² + bx + c = 0

  • a = 5
  • b = -4
  • c = 2

I hope this helps ✅(◠‿◕)

WILL GIVE BRAINLIEST IF SOLVED IN 10 MINS : Solve each equation with the quadratic :
Lady_Fox [76]

Answer:

5. x = -1 or x = -3

6. b = -2 or b = 6

7. n = 5 or n = 4

Step-by-step explanation:

5. x² + 4x + 3 = 0

Factorize

x² + 3x + x + 3 = 0

x(x + 3) +1(x + 3) = 0

(x + 1)(x + 3) = 0

Set each of the factors equal to zero and solve for x

x + 1 = 0 or x + 3 = 0

x = -1 or x = -3

6. b² - 4b - 14 = -2

Put all terms on one side of the equation leaving zero on one side

b² - 4b - 14 + 2 = 0

b² - 4b - 12 = 0

Factorize

b² - 6b + 2b - 12 = 0

b(b - 6) +2(b - 6) = 0

(b + 2)(b - 6) = 0

Set each of the factors equal to zero and solve for b

b + 2 = 0 or b - 6 = 0

b = -2 or b = 6

7. n² = 9n - 20

Put all terms on one side of the equation leaving zero on one side

n² - 9n + 20 = 0

n² - 5n - 4n + 20 = 0

n(n - 5) -4(n - 5) = 0

(n - 5)(n - 4) = 0

Set each of the factors equal to zero and solve for b

n - 5 = 0 or n - 4 = 0

n = 5 or n = 4
