7.2x-11=-47

7.2 x - 11 = - 47

x = - 5

Solution steps

7.2 x - 11 = - 47

Multiply both sides by

10

72 x - 110 = - 470

Move

110

to the right side

72 x = - 360

Divide both sides by

72

x = - 5

2 x - 5 (x - 3) = 2 (x - 10)

\frac{x}{4} + 3 = \frac{1}{2} (1 - \frac{x}{3})

- \frac{1}{4} + \frac{3}{4} a = - (- \frac{7}{4} a - 1)

lo g_{10} (\frac{1}{1000}) = x

r - 2 = - \frac{2}{5} r + \frac{7}{10} r + \frac{3}{2}
