Question

18=7x + 3-4x

23=9x + 5 - 6x
b - 4 + 6b = 23
b-1 +5b +34
30 = 5x + 3 - 2x
11= 8x + 3 - 6x
6(5x-2) = 78



can yall please help me solve these equations?

Answer 1

1. 18=7x + 3-4x (x = 5)

2. 23=9x + 5 - 6x (x = 6)

3. b - 4 + 6b = 23 (b = 27/7)

4. b-1 +5b =34 (b = 35/6)

5. 30 = 5x + 3 - 2x (x = 9)

6. 11= 8x + 3 - 6x (x = 4)

7. 6(5x-2) = 78 (x = 3)

Answer 2

x = 5

x = 6

b ≅ 2.714...

b = 5.5

x = 11

x = 7

x = 2.2

You're welcome.
