Answer: x = 0
Step-by-step explanation:
4x − 3 + x = 7x − 3
Step 1: Simplify both sides of the equation.
4x − 3 + x = 7x − 3
4x + −3 + x = 7x + −3
(4x + x) + (−3) = 7x − 3(Combine Like Terms)
5x + −3 = 7x − 3
5x − 3 = 7x − 3
Step 2: Subtract 7x from both sides.
5x − 3 − 7x = 7x − 3 − 7x
−2x − 3 = −3
Step 3: Add 3 to both sides.
−2x − 3 + 3 = −3 + 3
−2x = 0
Step 4: Divide both sides by -2.
-2x/-2 = 0/-2
x = 0
Answer: 4 roots
Step-by-step explanation: Just look at the highest power and that will tell you the amount of roots, unless there are imaginary roots
3 - 5n = -22
You're essentially just trying to get "n" isolated, or by itself.
So, in order to do that, we must move anything that doesn't have a variable in it onto the other side of the equal sign.
To do that, we must subtract 3 from both sides.
-5n = -22 - 3
Then, we simplify our equation.
-5n = -25
Then, we have to divide both sides by -5, so that we get the answer for "n."
-5n ÷ -5 = -25 ÷ -5
Simplify this.
n = -5

Answer:
y = 1x - 1
Step-by-step explanation:
y = mx + b
m is slope
slope = change in y / change in x = (3 - 2) / (4 - 3) = 1/1 = 1
m = 1 so equation is now y = 1x + b
To find b, substitute any value from the table. Let's use (3,2)
y = 1x + b
2 = 1(3) + b
2 = 3 + b
-1 = b
So equation is y = 1x - 1
