3x+15=3(x+5)

3x+15=3x+15

3x-3x=15-15

Therefore x can be equal to any value.

Solve each equation x+2y=1 and -x+y=2
Rudiy27

Answer:

x = -1, y = 1

Step-by-step explanation:

x + 2y = 1

Subtract 2y from both sides

x + 2y - 2y = 1 - 2y (simplify) -> x= 1 - 2y

----

-x + y = 2

Subtract y from both sides

-x + y - y + 2 - y (simplify) -> -x = 2 - y

Divide both sides by -1

\frac{-x}{-1} = \frac{2}{-1} - \frac{y}{-1} (simplify) -> x = -2 + y

a number consists of two digits. one of the digits is greater than the other by 5 when the digits are reversed the number become
lana [24]

Answer:

The number is 72.

Step-by-step explanation:

Let the digits be x and x - 5 where x  is the first digit.

(As the number reversed = 3/8 of the original number the first digit must be the largest),

Consider the reverse digit number:

The original number = 10x + (x - 5) so the reverse number is 10(x - 5) + x and

10(x - 5) + x  = 3/8(10x + (x - 5))

11x - 50 = 3/8(11x - 5)      

11x - 50 = 33/8 x - 15/8              Multiply through by 8:

88x - 400 = 33x - 15

55x = 385

x = 7

and x-5 = 2.
