4x-7(x+3)=-36

4 x - 7 (x + 3) = - 36

x = 5

Solution steps

4 x - 7 (x + 3) = - 36

Expand

- 7 (x + 3) : - 7 x - 21

4 x - 7 x - 21 = - 36

Add similar elements:

4 x - 7 x = - 3 x

- 3 x - 21 = - 36

Move

21

to the right side

- 3 x = - 15

Divide both sides by

- 3

x = 5

- 6.5 = p + 3.9

- \frac{5}{4} s = - 9

2 x - 9 = - 7 x

8 = \frac{n}{7}

4.25 + x = 7.5
