Answer:
-7x - 14
Step-by-step explanation:
By simplifying the expression:
-3(2x+5) - (x - 1)
-6x-15 -x + 1
-7x - 14
Answer:
-7x - 14
Step-by-step explanation:
You can use the distributive property to find an equivalent expression.
Distribute -3 to 2x + 5.
(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15
Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)
(-1 × x) + (-1 × -1) = -x + 1
You can simplify the expression.
(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14
