Question

como resuelvo este ejercicios 3×=180
8×=296
17×=289
15×=450
3×-50=70
7×48=22
17×-47=259
13×_430=974

Answer 1

$8x = 296 \\ x = 296 \div 8 \\ x = 37$

$3x = 180 \\ x = 180 \div 3 \\ x = 60$
$17x = 289 \\ x = 289 \div 17 \\ x = 17$

$15x = 450 \\ x = 450 \div 15 \\ x = 30$

$3x - 50 = 70 \\ 3x = 70 + 50 \\ 3x = 120 \\ x = 120 \div 3 \\ x = 40$

$7x - 48 = 22 \\ 7x = 22 + 48 \\ 7x = 70 \\ x = 70 \div 7 \\ x = 10$
en esta no sabia si te falto poner el signo a 48 y le puse -48

$17x - 47 = 259 \\ 17x = 259 + 47 \\ 17x = 306 \\ x = 306 \div 17 \\ x = 18$

$13x - 430 = 974 \\ 13x = 974 + 430 \\ 13x = 1404 \\ x = 1404 \div 13 \\ x = 108$

espero haberte ayudado
