0.18(5x - 4) = 0.50x + 0.8

0.90x - 0.72 = 0.50x + 0.8

On transposing 0.50x to **LHS **and 0.80 to **RHS**, we get

0.90x - 0.50x = 0.72 + 0.8

0.40x = 1.52

x = 3.8

**Check:**

**Taking LHS**

0.18(5x - 4)

On substituting x = 3.8, we get

0.18(5 x 3.8 - 4) = 2.7

**Taking RHS**

0.50x + 0.8

On substituting x = 3.8, we get

0.50 x 3.8 + 0.8 = 2.7

**We got LHS=RHS**
