5x-(6-4)x=90-69

5 x - (6 - 4) x = 90 - 69

x = 7

Solution steps

5 x - (6 - 4) x = 90 - 69

Subtract the numbers:

6 - 4 = 2

5 x - 2 x = 90 - 69

Add similar elements:

5 x - 2 x = 3 x

3 x = 90 - 69

Subtract the numbers:

90 - 69 = 21

3 x = 21

Divide both sides by

3

x = 7

5 (x - 3) = - 3 (2 x + 5)

\frac{x}{3} = 1.5 - x

7 (2 k + 4) - (3 k + 1) = 49

6 x - 2 = 34

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