If you would like to calculate 0.4 * x - 0.8 - 3 * x + 0.5 * x - 1.2, you can do this using the following steps:
0.4 * x - 0.8 - 3 * x + 0.5 * x - 1.2 = (0.4 * x - 3 * x + 0.5 * x) - 0.8 - 1.2 = - 2.1 * x - 2
The correct result would be - 2.1 * x - 2.
Answer:
Hello! I think x= 1.6 or 1.3 in this situation
Step-by-step explanation:
The fact that the number 7 on the left quadrilateral is 6.3, and the 4's are 3.6, I have come to the conclusion that x equals either 1.6 or 1.3.
Answer: x = -5
Step-by-step explanation: To solve this equation, we start by distributing the -4 through the parentheses on the left side.
So we have -4 times x which is -20x and -4 times -5 which is positive 20. So our equation now reads -20x + 20 = 120.
Solving from here, we subtract 20 from both sides of the equation and we have -20x = 100 and dividing both sides by -20, we find that x = -5.
Although I will not provide work to check our answer, the great thing about solving equations is that your can always check your answer by substituting what you got as a final answer into the original equation.
