Уравнение 6*X+8=14+30 5*(X+4)-43=17 20+4*X=52

Question

Уравнение 6*X+8=14+30
5*(X+4)-43=17
20+4*X=52

Answer 1

1)6х+8=14+30
6х=14+30-8
6х=36
х=36:6
х=6
2)5*(х+4)-43=17
5х+20-43=17
5х=17-20+43
5х=40
х=40:5
х=8
3) 20+4х=52
4х=52-20
4х=32
х=32:4
х=8

Answer 2

6х+8=14+30
6х=14+30-8
6х=36/:6
х=6
5(х+4)-43=17
5х+20-43=17
5х=17-20+43
5х=40/:5
х=8
20+4х=52
4х=52-20
4х=32/:4
х=8
