5. use a system of equations and a graphing calculator to solve 1.1x + 1.5 = -4.5x + 5.7
x= [ a 0.50 b 0.75 c
1.25)

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

Therefore x=0.75

Therefore option B) 0.75 is correct
