For your first question the answer is C(-2) and your next question the answer is A(-28)
Remember you can do anything to an equaiton as long as you do it to both sides
7x-4=5x+15
minus 5x both sides
2x-4=15
add 4 both sides
2x=19
divide by 2
x=19/2
14 will be your whole number and your fraction would be 63/100, so the entire thing as a mixed number is 14 63/100
First solve to your equation by step by step.
1/5(2x-10)+4x=-3(1/5x+4)
= x=-2
Answer is x=-2
