(3a)/4+(2a-4)/6 = 5/4

\frac{3 a}{4} + \frac{2 a - 4}{6} = \frac{5}{4}

a = \frac{23}{13}

Decimal Notation

a = 1.76923 \dots

Solution steps

\frac{3 a}{4} + \frac{2 a - 4}{6} = \frac{5}{4}

Multiply by LCM

9 a + 4 (a - 2) = 15

Expand

4 (a - 2) : 4 a - 8

9 a + 4 a - 8 = 15

Add similar elements:

9 a + 4 a = 13 a

13 a - 8 = 15

Move

8

to the right side

13 a = 23

Divide both sides by

13

a = \frac{23}{13}

x, y - 3 = - 4 (x - 5)

x = \frac{- 2 + 6161}{7}

\frac{x}{3} + 1 = 7

2 (x - 4) = 5 x + 7

3 (x - 1) - 2 (2 x + 1) = 8 (x - 1)
