Question

2×7+{2×2×1×[2×7×2+(x×1+1×2):(2×1×3)]-5}:5×1=1×7+3×2×5

Answer 1

2×7+{2×2×1×[2×7×2+(x×1+1×2):(2×1×3)]-5}:5×1=1×7+3×2×5

14+{4×[28+(x+2):6]-5}:5 = 7+30
{4×[28+(x+2):6]-5}:5 = 37-14
{4×[28+(x+2):6]-5}:5 = 23
{4×[28+(x+2):6]-5} = 23 × 5
4×[28+(x+2):6]-5 = 115
4×[28+(x+2):6] = 115+5
4×[28+(x+2):6] = 120
[28+(x+2):6] = 120:4
28+(x+2):6 = 30
(x+2):6 = 30-28
(x+2) : 6 = 2
x+2 = 2×6
x + 2 = 12
x = 12-2
x = 10
