0.4=0.38(u+1)-0.22u

0.4 = 0.38 (u + 1) - 0.22 u

u = \frac{1}{8}

Decimal Notation

u = 0.125

Solution steps

0.4 = 0.38 (u + 1) - 0.22 u

Switch sides

0.38 (u + 1) - 0.22 u = 0.4

Multiply both sides by

100

38 (u + 1) - 22 u = 40

Expand

38 (u + 1) - 22 u : 16 u + 38

16 u + 38 = 40

Move

38

to the right side

16 u = 2

Divide both sides by

16

u = \frac{1}{8}

9 + 4 (x + 1) = 25

\frac{5}{7} (k + 5) = - 7

21 - (2 v + 17) = - 7 - 3 v

4 (4 x + 1) = - 60

- 7 y = 35
