Question

решите уравнение х-7/12=3/4;х-1/6=1/9;х-3/5=3/8

Answer 1

х-7/12=3/4
х=3/4+7/12
х=9/12+7/12
х=16/12
х=1 4/12=1 1/3

х-1/6=1/9
х=1/9+1/6
х=6/54+9/54
х=15/54

х-3/5=3/8
х=3/8+3/5
х=15/40+24/40
х=39/40

Answer 2

=3/4+7/12
×=3×3/3×4+7/12
x=9/12+7/12
x=3/4;

x=2×1/2×9+3×1/3×6
x=2+3/18
x=5/18;

x=5×3/5×8+8×3/8×5
x=15+24/40
x=39/40
