What is the sum of the following equatiioin? 10x+20y+5x=?
Vsevolod [243]

Answer:

15x + 20y

Step-by-step explanation:

First, we need to combine like terms,

10x + 20y + 5x

15x + 20y

Since x and y are different variables, we cannot combine them, meaning that the answer is,

15x + 20y

the sum of two numbers is 123. when the larger number is added to 5 times the smaller, the sum is 343. find the numbers.​
vovikov84 [41]
Create a system of equations
x + y = 123
5x + y = 343

I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55

Plug in
x + y = 123
55 + y = 123
y = 68

Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
