Step-by-step explanation:
Hi there,
The sum of two numbers is 8.
x + y = 8
If three times the first number
is equal to the second number.
3x = y
Replace the y in top equation with 3x
x + 3x = 8
4x = 8
x = 2
Substitute x = 2 in first equation
2 + y = 8
y = 8 - 2
y = 6
{2,6}
Hope this helps :-)
Equations:
A + T = 735 naira
A = T + 95
A + T = 735
A - T = 95
Add and solve for A:
2A = 830
A = 415 naira
T = 735-415 = 320
Answer: 32 students
Step-by-step explanation: 8 x 4 = 32
