Question

5x - 3 (3-x/ 4 )= 7 x /2 - 3​

Answer 1

Respuesta:

5x - 3 (3-x/ 4 )= 7 x /2 - 3​

5x - 9 +3x/4= 7x/2 - 3

40x - 72 +6x= 28x - 24

46x - 28x = - 24+72

18x= 48

X= 48/18

X = 8/3

Comprobamos

5x - 3 (3-x/ 4 )= 7 x /2 - 3​

5(8/3) - 3(3 - (8/3)/4) = 7(8/3)/2 - 3

40/3 - 3(3 - 2/3) = (56/3)/2 - 3

40/3 - 3(9/3-2/3) = 28/3 - 3

40/3 - 3(7/3)= 28/3 - 9/3

40/3 - 21/3= 19/3

19/3 = 19/3
