Trying to work out this problem. can't find out what x is.
0.5(−2.5x − 4.7) = 16.9
1 answer:
So here you first want to open up the parenthesis by using the distributive property. (Is that what it's called)
So basically multiply each and every number by 0.5.
So 0.5 * -2.5x - 0.5 * 4.7 = 16.9
Is what you get after doing that.
And then just multiply the numbers
So
-1.25 * x - 2.35 = 16.9
Add 2.35 to both sides
-1.25 * x = 19.25
And then divide both sides by -1.25 to get
x = - 15.4
So there's your answer.
(Sorry I took so long btw)

We want to use elimination to solve
y = 0 (1)
x + y = 40 (2)
Multiply (1) by -1 to eliminate y.
-y = 0 (3)
Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40
Answer: Multiply by -1.
