Answer:
1. (4)x + y =50
2x + 4y =172
2. (1)x + y =8
150x + 50y =800
3. (1)x + y =20
25 + 10y =290
Step-by-step explanation:
Just trust me and its too much work explaining and im lazy so just ask your teacher or a friend if you can.
-1 and 4 I think is the answer is the function
Answer:
x < 3
Step-by-step explanation:
You answer is 3 and here's why...
7x + 5 - 3x - 7 = 10
First you must collect like terms
And that gives us
4x - 2 = 10
Next you must simplify by removing additives
4x - 2 + 2 = 10 + 2
4x = 12
Now you must divide
4x/4 = 12/4
x = 3
