Answer:
The numbers are 87 and 106
Step-by-step explanation:
x + y = 193
x - y = 19
Add y to both sides of the equation
x = 19 + y
Substitute new value for x into first equation
19 + y + y = 193
Add y's together
19 + 2y = 193
Subtract 19 from both sides of the equation
2y = 174
Divide both sides of the equation by 2
y = 87
193 - 87 = 106
The numbers are 87 and 106
Hope this helps :)
