Question

Как решать уравнение х-250:5=740. И. Х+80•4=560 И 70•3-х=160 и 720:90+х=43

Answer 1

$1) \ x - 250 div 5 = 740 \ x = 740 +50 \ x = 790 \ \ 2) \ x + 80 times 4 = 560 \ x = 560 - 320 \ x = 240 \ \ 3) \ 70 times 3 - x = 160 \ - x = 160 - 210 \ -x = - 50 \ x = 50 \ \ 4) \ 720 div 90 + x = 43 \ x = 43 - 8 \ x = 35$
