Answer:
answer is A) -1.69
Explanation:
-1.4x=5(x+2.16)
multiply 5 by equation in bracket.
-1.4x= 5x+10.8
move 5x to the left side because of x and the equation will look like this -1.4x-5x=10.8
subtract -5x from -1.4x and you'll get -6.4x
-6.4x=10.8
divide both sides by -6.4x and your answer will be x=-1.6875 round it to get -1.69
