Question

Kakakkk...bantuu yaa please buat bahan besok :(

Answer 1

2/3(5a+2)=2(a+2)
10a/3 +4/3 = 2a+4
10a/3 - 2a = 4 - 4/3
10a/3 - 6a/3 = 12/3-4/3
4a/3 = 8/3
a = 8/3*3/4
a = 8/4
a = 2

Answer 2

1) ⅔ (5a + 2) = 2 (a + 2)
10/3 a + 4/3 = 2a + 4
10/3 a - 2a = 4 - 4/3
10/3 a - 6/3 a = 12/3 - 4/3
4/3 a = 8/3
a = 8/3 ÷ 4/3
a = 8/3 × 3/4
a = 2

2) {(2x - 1)/3} + {(6x + 4)/2} = (4x + 3) ---> ×6
2(2x - 1) + 3(6x + 4)=6(4x+ 3)
4x - 2 + 18x + 12 = 24x + 18
22x + 10 = 24x + 18
22x - 24x = 18 - 10
-2x = 8
x = -4
