I bought 3 bags of marbles. My friend bought 1 bag and he also had 24 loose marbles. We discovered that we had exactly the same number of marbles. a) Make up an equation to show this information. (let x be the number of marbles in 1 bag) b) Solve the equation to determine how many marbles there are in each bag.

Q: Solve the following equations. a. -x+1=7 b. 1-x= -11 C. X-7=

A: (a) - x + 1 = 7 So, x = 1 - 7  So, x = - 6

Q: Solve: 2x-1 15

A: To solve: 2x-1=15 Solution: We know that if x=a then x=±a. Using above property, 2x-1=152x-1=±15…

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
