Step-by-step explanation:
x + y = 50
x - y = 4
x = y + 4
let's use that as substitute in the first equation
y + 4 + y = 50
2y = 46
y = 46/2 = 23
=>
x = y + 4 = 23 + 4 = 27
the 2 numbers are 23 and 27.
let the 2 numbers be x and x + 4 as their deference is 4.
their sum = 50
now,
→ x + x + 4 = 50
→ 2x + 4 = 50
→ 2x = 50 - 4 = 46
→ x = 46/2 = 23
therefore two numbers are,
x = 23
x + 4 = 23 + 4 = 27
hope this answer helps you dear...take care and may u have a great day ahead!
Answer:
42/8= 5 2/8
explanation:
8*5=40 42-40=2
therefore
• subtract eqn(b) from eqn(a);
• find x :
3- 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
4- 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
7- 7, 14, 21, 28, 35, 42, 49, 56, 63, 70
