Umm can u please say something more specific

How to solve a inequality of -3x+3<6 Please help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In the equation 10a + 6c = $80, you can replace either the variable 'a' or the variable 'c' with a number. To determine which variable you can replace, you need more information or context about the problem or scenario this equation represents.

If you have additional information that allows you to determine the value of one of the variables, you can substitute that value into the equation. For example, if you know the value of 'c' is 5, you can substitute 'c' with 5 and solve for 'a':

10a + 6(5) = 80
10a + 30 = 80
10a = 80 - 30
10a = 50
a = 50/10
a = 5

In this case, you found that 'a' is equal to 5. Similarly, if you had a known value for 'a', you could substitute that value and solve for 'c'.
