Answer:
n=3
Step-by-step explanation:
So the question we are to solve is to be solved by collecting like terms and by division
So let's solve the question
-5n+8=-7
So let's solve
-5n+8=-7
Substrate 8 from both sides
-5n=-15
So let's make n the subject of formula by dividing both sides by -5
n=3
Therefore the final answer for the given question is 3
4(m + 2) expanded is 4 x m and 4 x 2
simplified: 4m + 8
128 = a + + 4(a + 10) + (a + 10)
128 = a + 4a + 40 + a + 10
128 = 6a + 50
128-50 = 6a
78 = 6a
13 = a
1st = a = 13
2nd = 4(a + 10) = 4(23) = 92
3rd = a + 10 = 23
