1). 5a+3=28
2). 7b + 5 = 61
3). 6a + 1 = 49
4). 4a + 11= 39
5). 4a + 5 =2a + 10
pake cara ya kaka

1.5a + 3 = 28
5a = 28-3
5a = 25
a = 25/5
a = 5
2.7b + 5 = 61
7b = 61 – 5
7b = 56
b = 56/7
b = 8
3.6a + 1 = 49
6a = 49-1
6a = 48
a = 48/6
a = 8
4.4a + 11 = 23
4a = 39-11
4a = 28
a = 28/4
a = 7
5.4a + 5 = 2a + 10
4a – 2a = 10-5
2a = 5
a = 5/2
a = 2,5
