Plis... banget kakak tolong jawab ya!!! pake cara ok...no.1-10

Answer 1

1 ] 2a+1=a-3
2a-a=-3-1
a=-4

2 ] 12+3a=5+2a
3a-2a=5-12
a=-7

3 ] 6-5y=94y
6-9=-4y+5y
y=-3

4 ] 7n+4=4n-17
7n-4n=-17-4
3n=-21
n=-7

5 ] 3(x+1)=2(x+4)
3x+3=2x+8
3x-2x=8-3
x=5

6 ] 4(3-2y)=15-7y
12-8y=15-7y
12-15=-7y+8y
7=-3

7 ] 7q=5q-12
7q-5q=-
2q=-12
q=-6

8 ] 18+7x=3(5-x)
10-4x=15-3x
10-15=-3x+4x
x=-5

9 ] 18+7x=2(3x-4)
18+7x=6x-8
7x-6x=-8-18
x=-26

10 ] 5x+7(3x+2)=6(4x+1)
5x+21x+14=24x+6
5x+21x-24x=6-14
2x=-8
x=-4
