Answer:
The two numbers are x = 8 and y = 5
Step-by-step explanation:
Let the two numbers be x and y
The difference of two numbers is 3 is represented as:
x - y = 3------------------Equation 1
Their sum is 13 is represented as:
x + y = 13----------------Equation 2
x - y = 3------------------Equation 1
Using method of Elimination by subtracting Equation 1 from Equation 2
x-x + y-(-y) = 13 - 3
2y = 10
y = 10/2
y = 5
Substituting y = 5 in Equation 2
x + 5 = 13
x = 13 - 5
x = 8
∴ The two numbers are x = 8 and y = 5
Answer:
148-13=135
4x+13= - 3.25
6x+2 = - 0.33
Step-by-step explanation:
1) SIMPLE SUBTRACTION

---------
2)
4x+13=0
4x= - 13
x= -13/4
x= - 3.25
3)
6x+2 = 0
6x= -2
x= -2/6
x = -0.33

Answer:
12, -12
Step-by-step explanation:
sqrt(144)
What number times itself = 144
12*12 = 144
Also -12*-12 = 144
