How to check the equation of 3x + 6 = 18?


3x+6=18
3x=12
x=4
Test: 3 × 4 + 6 = 12 + 6 = 18



1 - (3 / 2x) = 3x + (5 / 2) is the answer 1 / 3? What are the steps to solve this equation and how to check it,


The answer is - 1 / 3, which can be checked directly



Solving equation (24-4x) × (8-2x) = 96


(24-4X)×(8-2X)=96
8×(6-X)×(4-X)=96
(6-X)×(4-X)=12
X^2-10X+24=12
X^2-10X+12=0
X^2-10X+25-25+12=0
(X-5)^2-13=0
(X-5-√13)(X-5+√13)=0
X = 5 + √ 13 or x = 5 - √ 13
