Answer:
Option B) 0.75 is correct
Therefore x=0.75
Step-by-step explanation:
Given system of equation is 1.1x+1.5=-4.5x+5.7
To solve the given system of equation :
1.1x+1.5=-4.5x+5.7
Subtracting with (-4.5x+5.7) on both sides we get
1.1x+1.5-(-4.5x+5.7)=-4.5x+5.7-(-4.5x+5.7) ( Subtraction property of equality )
1.1x+1.5+4.5x-5.7=-4.5x+5.7+4.5x-5.7 ( using Distributive property )
5.6x-4.2=0 ( adding the like terms )
5.6x-4.2+4.2=0+4.2 ( Addition property of equality )
5.6x+0=4.2
5.6x=4.2
[tex]x=\frac{4.2}{5.6}[/tex]
[tex]=0.75[/tex]
Therefore x=0.75
Therefore option B) 0.75 is correct
