4(x-9)-1/2 (x-9)=21

4 (x - 9) - \frac{1}{2} (x - 9) = 21

x = 15

Solution steps

4 (x - 9) - \frac{1}{2} (x - 9) = 21

Multiply both sides by

2

7 (x - 9) = 42

Expand

7 (x - 9) : 7 x - 63

7 x - 63 = 42

Move

63

to the right side

7 x = 105

Divide both sides by

7

x = 15

x - 4 \frac{2}{3} = \frac{1}{3}

a, y = a e^{x} + b e^{3 x}

4 x - 9 = 11

x, 3 x + y = 17

0.4 + 0.5 z = 0.6 z + 0.1 z + 2
