Kira John and Ryan sent a total of 112 text messages during the weekend. Kira sent 8 fewer messages than Ryan. John sent 4 times
Softa [21]

Answer:

Kirasent 16 and Ryan sent 96

Step-by-step explanation:

I got this because Kira is x-8 and Ryan is 4x. 4x-x-8=112 is equal to 5x=120. So x=24.Kira has 16 when plugging in x and Ryan has 96 because 4 times 24 is 96.

Solve the equation... 10x - 12 = 48 - 2x
hjlf
If you would like to solve the equation 10 * x - 12 = 48 - 2 * x, you can calculate this using the following steps:

10 * x - 12 = 48 - 2 * x
10 * x + 2 * x = 48 + 12
12 * x = 60   /12
x = 60 / 12
x = 5

The correct result is 5.
