Ответ:
The larger number is 8
Step-by-step explanation:
Let
x > the smaller number
y > the larger number
we know that
x+y=10
y=10-x > equation A
y=4x > equation B
Solve by substitution
substitute equation B in equation A and solve for x
4x=10-x
4x+x=10
5x=10
x=2
Find the value of y
y=4x> y=4(2)=8
therefore
The smaller number is 2 and the larger number is 8
