Question

1. -7x+14 = 8x-16
2. -9a = -7a + 22
3. -6+ 14 = -10
4. 7-3a = 2a-8
5. 9x + 3x = -36

Answer 1

1. -7x + 14 = 8x - 16
-7x + -8x = -16-14
-15x= -30
x=-30:-15
x=2
2.-9a=-7a+22
-9a+7a=22
-2a=22
a=22:2
a=11
4.7-3a=2a-8
3a-2a=-8-7
a=-15
5.9x+3x=-36
12x=-36
x=-36:12
x=-3

yang no.3 gak ngerti

Answer 2

1.) -7x -8x = -16 -14
-15x = -30
x = 2
2.) -9a + 7a = 22
-2a = 22
a = -11
3.) soalnya kurang jelas
4.) -3a -2a = -8 -7
-5a = -15
a = 3
5.) 12x = -36
x = -3
