Answer:
x = 12
Step-by-step explanation:
3(x - 1) - 2x = 9 remove the brackets using the distributive property
3x - 3 - 2x = 9 Collect 3x and -2x (Collect like terms)
3x - 2x - 3 = 9 Use the reverse of the distributive property to get x
x(3 - 2) - 3 = 9 Do what is inside the brackets
x - 3 = 9 Add 3 to both sides (additive inverse)
x - 3 + 3 = 9+3 Combine like terms on the left
x = 12
Answer:
thanks I guess for the points
Step-by-step explanation:
2x - 3 = sally's berries
