Question

[(a-200:5x4)x5+3]x2=726

Answer 1

[ ( a - 200 : 5 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 40 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 160 ) × 5 + 3 ] × 2 = 726

[ ( a - 160 ) × 5 + 3 ] = 726 : 2

[ ( a - 160 ) × 5 + 3 ] = 363

[ ( a - 160 ) × 5 ] = 363 - 3

[ ( a - 160 ) × 5 ] = 360

a - 160 = 360 : 5

a - 160 = 72

a = 72 + 160

a = 232

Answer 2

[(a -200÷5×4)×5+3]×2=726

[(a-40×4)×5+3]×2=726

[(a-160)×5+3]=726÷2

[(a-160)×5+3=363

(a-160)×5=363-3

(a-160)×5=360

(a-160)=360÷5

a-160=72

a=160+72

a=232
