Question

x/3 + 3-2x/4 = 3 + x/6 fracinada

Answer 1

Resposta:

3/4 = x

Explicação:

x/3+(3-2x)/4 = (3+x)/6

[12÷3×x]/12+[12÷4×(3-2x)]/12 = [12÷6×(3+x)]/12

[4×x]/12+[3×(3-2x)]/12 = [2×(3+x)]/12

4x/12+(9-6x)/12 = (6+2x)/12

(4x+9-6x)/12 = (6+2x)/12

(9-2x)/12 = (6+2x)/12

9-2x = 6+2x

9-6 = 2x+2x

3 = 4x

3/4 = x
