0.4x + 0.28 = 0.6x - 4.2
0.4 x - 0.6x = - 4.2 - 0.28
- 0.2x = -4.48
x = 22.4

Answer: Did you find an answer yet?? Lol
Step-by-step explanation:
We will use a method of substitution.
y = 5/2 x + 2
2 y = 5 x + 4 ⇒ 2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0 ⇒ x, y ∈ R
Answer: D)
This system has infinitely many solutions.
Polynomials are set of expressions with variables that are usually used in operations.
*2x^2 +3x-2
2x^4+3x^3(2x^3+2x)=4x^7+4x^5+6x^6+6x^4
*(^ is the raised exponent)
