2x-3/2 + (2x+3x-1/4) =1/8

Dear student

2 x - \frac{3}{2} + (2 x + 3 x - \frac{1}{4}) = \frac{1}{8} \Rightarrow 2 x - \frac{3}{2} + 5 x - \frac{1}{4} = \frac{1}{8} \Rightarrow 7 x = \frac{1}{8} + \frac{3}{2} + \frac{1}{4} \Rightarrow 7 x = \frac{1 + 12 + 2}{8} \Rightarrow 7 x = \frac{15}{8} \Rightarrow x = \frac{15}{8} \times \frac{1}{7} \Rightarrow x = \frac{15}{56}
