Question

реши уравнения. х+2=7×9, х-20=63÷9, х+700=890

Answer 1

1.
$x + 2 = 7 times 9 \ x + 2 = 63 \ x = 63 - 2 \ x = 61 \ 61 + 2 = 7 times 9$
2.
$x - 20 = 63 div 9 \ x - 20 = 7 \ x = 20 + 7 \ x = 27 \ 27 - 20 = 6 div 9$
3.
$x + 700 = 890 \ x = 890 - 700 \ x = 190 \ 190 + 700 = 890$

Answer 2

Х+2=7*9
х+2=63
х=63-2
х=61

х-20=7
х=7+20
х=27


х+700=890
х=890-700
х=190
