2*{12+3*[60-3*(27-4*3)]}-5x=64

*=înmulțire

Answer 1

2*{12+3*[60-3*(27-4*3)]}-5x=64

2*{12+3*[60-3*(27-12)]}-5x=64

2*[12+3*(60-3*15)]-5x=64

2*[12+3*(60-45)]-5x=64

2*(12+3*15)-5x=64

2*(12+45)-5x=64

2*57-5x=64

114-5x=64

5x=114-64

5x=50

x=50÷5

x=10

Answer 2

2×{12+3×[60-3×(27-4×3)]}-5x=64

2×{12+3×[60-3×(27-12)]}-5x=64

2×[12+3×(60-3×15)]-5x=64

2×[12+3×(60-45)]-5x=64

2×(12+3×15)-5x=64

2×(12+45)-5x=64

2×57-5x=64

114-5x=64

5x=114-64

5x=50

x=50÷5

x=10
