Answer:
n = (123 - 3a) / 0.1
Step-by-step explanation:
Given:
3a + 0.1n = 123
Solve for n
3a + 0.1n = 123
Subtract 3a from both sides
3a + 0.1n - 3a = 123 - 3a
0.1n = 123 - 3a
Divide both sides by 0.1
n = (123 - 3a) / 0.1
The resulting equation if 3a + 0.1n = 123 is solved for n is n = (123 - 3a) / 0.1

Answer:
12x+12 = 7x+56
Step-by-step explanation:
12 / (x+8) = 7 / (x+1)
We can use cross products
12 (x+1) = 7(x+8)
Distribute
12x+12 = 7x+56
