5=|(2x)/7+4/7 |-3

5 = \frac{2 x}{7} + \frac{4}{7} - 3

x = - 30 or x = 26

Solution steps

5 = \frac{2 x}{7} + \frac{4}{7} - 3

Switch sides

\frac{2 x}{7} + \frac{4}{7} - 3 = 5

Move

3

to the right side

\frac{2 x}{7} + \frac{4}{7} = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{2 x}{7} + \frac{4}{7} = - 8 or \frac{2 x}{7} + \frac{4}{7} = 8

\frac{2 x}{7} + \frac{4}{7} = - 8 or \frac{2 x}{7} + \frac{4}{7} = 8

x = - 30 or x = 26

16 y - 8 (3 y - 4) = - 48

\frac{9 n ^{2}}{15 n ^{2}}

4 - 3 (1 - x) \leq 3

5 - \frac{1}{x} \leq 4

18 x^{4} + 15 x^{3}
