If a = 24 and b = -6 then 24--6 = 30 because --6 = +6

5

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.

Y = mx + b such as y = 3x + 5 the y-intercept (b) = 5

If a = 24 and b = 6, then a - b = 24 - 6 = 18

If a = 26 and b = 6 then a - b = 20.

B/5 = 6 means that 6 x 5 = B 6 x 5 = 30 Therefore, B = 30
