If a + b = 6, what is the value of 3a + 3b?
2 X 6 = 12
a = 6b = 9a + b = 6 + 9 = 15
30
15
30
If a = 24 and b = 6, then a - b = 24 - 6 = 18
If a + b = 6, what is the value of 3a + 3b?
If a = 24 and b = -6 then 24--6 = 30 because --6 = +6
54
6
2 X 6 = 12
a = 6b = 9a + b = 6 + 9 = 15
6 b/c its distance to zero is 6
That would depend on the value of A.
Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE
For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.
