Answer:
x=14
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−9)=20
Step 1: Simplify both sides of the equation.
4(x−9)=20
(4)(x)+(4)(−9)=20(Distribute)
4x+−36=20
4x−36=20
Step 2: Add 36 to both sides.
4x−36+36=20+36
4x=56
Step 3: Divide both sides by 4.
4x
4

if so gimme some brainiest
Answer: You can see it does matter in what order you solve the equation. ... Just like when you are solving equations with whole numbers, solving equations with fractions has the same order of operations. The order of operations is the order in which you solve the problem. If numbers are in parentheses, you do them first.
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
