Hi there! With equations like this we want to get our variable on one side and and our constant on the other.
So with 2x + 3 = -7 you'd subtract the constant 3 from both sides of the equal sign to get 2x = -10, then you'd divide both sides by 2 to get x = -5. If you double check your work by replacing x in the original equation with our answer we'd find that 2(-5) + 3 = -7 is correct.
Hope you find this helpful :)
Answer:
hmmmm I don't know It really depends on the person who is writing it
Step-by-step explanation:
but if you really want to know most people have different ways of telling people how they got to their answer
<span>3 is to 4 as 12 is to x, or 3/4 = 12/x </span>
