Answer:
one solution
Step-by-step explanation:
x + y = 6 so 2x + 2y = 12
That means 3y = 9 so there is only one solution. x also equals 3
For this case we must evaluate the following expression:
14 + (- 8) ÷ 2 * -3
According to the method of algebraic resolution, called PEMDAS, the divisions and multiplications must be made from left to right, before the addition and subtraction, then:
14 + (- 4) * - 3 =
We eliminate the parenthesis keeping in mind that 

Equal signs are added and the same sign is placed:

Answer:
26
Answer:
1 / 24
Step-by-step explanation:
= > 3/8 - 2/6
=> {(3 x 3)/(8 x 3)} - {(2x4)/(6x4)}
=> 9/24 - 8/24
=> ( 9 - 8 ) / 24
= 1 / 24 ANS
Let the numbers be x and y; x being the larger number and y being the smaller.
Given,
x + y = 2* (x - y)
x + y = 2x - 2y
x = 3y
Also given,
x = 6 + 2y
3y = 6 + 2y
--- y = 6
Thus, x = 3y = 3*6 = 18.
Therefore, the numbers are 18 and 6.
