4x + y = 1
-2x - y = -8
2x = -7
x = -7/2
2(-7/2) + y = 8
-7 + y = 8
y= 15

Answer:
52 = 8n + 4
4(2n + 1) = 52
4 = 52 – 8n
n = 6
Step-by-step explanation:
52 = 8n + 4
52 - 4 = 8n
48 = 8n
n = 48/8
n = 6
4(2n + 1) = 52
8n + 4 = 52
8n = 52 - 4
8n = 48
n = 48/8
n = 6
4 = 52 – 8n
4 - 52 = -8n
-48 = -8n
n = -48/-8
n = 6
4n = 48
n = 48/4
n =12
n = 6
52 = 8n + 4 is equivalent to 4(2n + 1) = 52 is equivalent to 4 = 52 – 8n is equivalent to n = 6
Answer:
t=8 so 8 years
Step-by-step explanation:
H=36
so
36=4t+4
36-4=32
32=4t
32/4=8
8=t
Check:
36=4(8)+4
36=32+4
36=36
