3x - 5y = 5 ——> 6x - 10y = 10
6x - 10y = 10
x + 10y = 4
——————-
5x = 6
x = 1.2
1.2 + 10y = 4
10y = 2.8
y = 0.28
so, x = 1.2 and y = 0.28
hope this helps :)
The answer would be 4 because your rounding to the whole. If your rounding to the tenth it would be 3.4

7 - 6y - 5x³ - 1 + x³ - 7 - 2y
<u>Step 2: Simplify</u>
- [Addition] Combine like terms (x³): -4x³ + 7 - 6y - 1 - 7 - 2y
- [Subtraction] Combine like terms (y): -4x³ - 8y + 7 - 1 - 7
- [Subtraction] Combine like terms: -4x³ - 8y - 1
I√49=7i
They are equal btw
