Tentukan a dan b yg memenuhi dari:
a. 3a+6-2a+7=15
b. 4b+6=2b-4![]()
a. 3a+6-2a+7=15
b. 4b+6=2b-4
Penjelasan dengan langkah-langkah:
a.) 3a+ 6 - 2a + 7 = 15
(3a - 2a) + 6 + 7 = 15
a + 13 = 15
a = 15- 13
a = 2
b.) 4b + 6 = 2b - 4
4b - 2b = -4 - 6
2b = -10
b = -10/2
b = -5
a. 3a + 6 - 2a + 7 = 15
→ 3a - 2a + 6 + 7 = 15
→ a + 13 = 15
→ a = 15 - 13
→ a = 2

b. 4b + 6 = 2b - 4
4b - 2b = - 4 - 6
2b = -10
b = [tex]\tt \frac{-10}{2}[/tex]
b = -5
