Question

решите уравнение: (410 -t) / 7+70=120

Answer 1

(410 - t) : 7 + 70 = 120
(410 - t) : 7 = 120 - 70
(410 - t) : 7 =  50
410 - t = 50 * 7
410 - t = 350
t = 410 - 350 
t = 60

Answer 2

$\frac{410-t}{7} +70=120 \\ \frac{410-t}{7} =120-70 \\ \frac{410-t}{7} =50 \\ 410-t=50*7 \\ 410-t=350 \\ t=410-350 \\ t=60$
