Solve 4a = 20
olya-2409 [2.1K]

Here's the solutions :

1. solve for a :

  • 4a = 20

  • a =  \dfrac{20}{4}

  • a = 5

2. solve for y :

  • 3y + 9 = 24

  • 3y = 24 - 9

  • 3y = 15

  • y =  \dfrac{15}{3}

  • y = 5

3. solve for y :

  • \dfrac{y}{3}  - 5 = 4

  • \dfrac{y}{3}  = 5 + 4

  • \dfrac{y}{3}  = 9

  • y = 9 \times 3

  • y = 27

4. solve for k :

  • 3 = 9 -  4k

  • 3 - 9 =  -4 k

  • - 6 =  - 4 k

  • k =  \dfrac{ - 6}{ - 4}

  • k =  \dfrac{3}{2}  \:  \:  \: or \:  \: 1.5

5. there's something wrong with this question.

6. solve for x :

  • 3x + 8 = 2

  • 3x = 2 - 8

  • 3x =  - 6

  • x =  \dfrac{ - 6}{3}

  • x =  - 2

i hope it helped...
