Answer: 48, 52
Step-by-step explanation:
The sum of the two numbers (x, y) is 100. This means that;
x+y=100
Their difference is 4, so;
y=x+4
Now, you can substitute that in for y;
x+(x+4)=100
Simplify;
2x+4=100
2x=96
x=48
Now, we plug in the value of x to the second equation;
y=48+4
y=52
Answer:
48 and 52
Step-by-step explanation:
We have a pair of simultaneous equations and will solve these using substitution.
x + y = 100 (1)
x - y = 4 (2)
Solve for x:
x+y=100 , x - y = 4
x=52
Substitute x with 52
(52) + y = 100 , (52) - y = 4
Simplify:
y = 48
