Question

Tolond di bantu ya kak,besok di kumpulin A sampai B pakai cara
Makasih

Answer 1

A
1. d
2.3x + 2 = 11
3x = 11-2
x = 9/3
x = 3
c. 3
3. 5x - 4 = 6x-9
5x-6x =-9+4
-x = -5
. x = 5
d. 5
4. 1/2(x+3)= 1/4(3x-1)
x+3/2 = 3x-1/4
dikalikan silang
2(3x-1)= 4(x+3)
6x-2= 4x +12
6x-4x = 12+2
2x = 14
x = 14/2
x = 7
c.7
5. x + 5 = 11
x = 11-5
x = 6
x+33= 6+33
= 39
b.39
6. 6x +1 <_ 4x +9
6x-4x <_ 9-1
2x <_ 8
x <_ 8/2
x <_ 4
b.1,2,3,4
7.2a + 10 > 3a -2
2a -3a > -2-10
-a > -12
a < 12
b.
maaf cuman sampai segini
