If n is 2, you substitute 2 for n and multiply 5(2)+8= 10 +8 = 18
Answer:
the answer is 62!
Step-by-step explanation:
multiply
1/2(4+X)+2=16
2+(0.5 x X) + 2 = 16
4 + (0.5 x X) = 16
0.5 x X = 12
X = 24
idk if u understand my working out - message me if u dont
hope it helped tho :)
To make it much easier, it should be converted to the slope-intercept form
y = mx + bTo do so, 14x + 34y = 1 turns to:
34y = -14x + 1Divide both sides by 34:

Answer:
10 years ago
Step-by-step explanation:
Let x be the number of years ago
x years ago,
Sonu's grandmother was 80 - x
Sonu was 20 - x
x years ago,
the grandmother was 7 times as old as Sonu
80 - x = 7(20 - x)
80 - x = 140 - 7x
6x = 60
x = 10
