Question

1). 37 + x =59 2). X-28 = 43 3). 3(X- 2) =6. 4). 15 + 3(x - 2) =3 5l. - 3( x - 4) =5x - 12.​

Answer 1

Ответ:

1) 37 + x =59

х=50-37

х=22

2)X-28 = 43

х= 43-28

х=15

3) 3(X- 2) =6

3х - 6 = 6

3х=6+6

3х=12

х=4

4)15 + 3(x - 2) =3

15+ 3х - 6 =3

3х+9=3

3х= 3 - 9

3х = -6

х= -2

5)

- 3( x - 4) =5x - 12

-3х +12= 5х -12

-3х - 5х = - 12 -12

-8х= - 24

х= 3
