Question

Jawablahsoal 1-4 berikut ini kalau anda bisa
01. 3x-2=7=
02.5(y-2)=5=
03.1/2x+3=2=
04.5-(4-3y)=22=

Answer 1

1) 3x-2=7
3x=7+2
3x=9
x=9/3
x=3

2) 5(y-2)=5
5y-10=5
5y=5+10
5y=15
y=15/5
y=3

3) 1/2x+3=2
1/2x=2-3
1/2x=-1
x=-1/1/2
x=-1.2/1
x=-2/1
x=-2

4) 5-(4-3y)=22
5-4+3y=22
1+3y=22
3y=22-1
3y=21
y=21/3
y=7

Answer 2

01. 3x-7:7= 3x :-) 02.5(y-2)-5= 2y 03.1/2x+3-2 = 1/2x 04.5-(4-3y) -22 = -26Y
