The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?
lorasvet [3.4K]

Answer:

104

Step-by-step explanation:

First, put the word equation into a numerical equation.

-4+5x=7x-212                            This is our equation

-4=2x-212                                  I subtracted 5x from both sides

208=2x                                     I added 212 to both sides

104=x                                         I divided both sides by 2
