-2(x + 3) = -2(x + 1) - 4
-2x - 6 = -2x - 2 - 4 <em>distributed -2 on the left and on the right</em>
-2x - 6 = -2x - 6
<u>+2x </u> <u>+2x </u>
-6 = -6
TRUE
Since this is a true statement, there are infinite solutions (aka All Real Numbers)

Answer:
-(x + 5)(3x + 1)
Step-by-step explanation:
Step 1: Factor out negative
-1(3x² + 16x + 5)
Step 2: Factor quadratic
-(x + 5)(3x + 1)
Answer:
n = 1/5
Step-by-step explanation:
Let's solve your equation step-by-step.
5(n−
1
/10
)=
1/
2
Step 1: Simplify both sides of the equation.
5(n−
1
/10
)=
1
/2
(5)(n)+(5)(
−1
/10
)=
1/2
(Distribute)
5n + −1
/2
=
1
/2
Step 2: Add 1/2 to both sides.
5n + −1
/2 + 1
/2 = 1
/2 + 1
/2
5n=1
Step 3: Divide both sides by 5.
5n
/5 = 1
/5
n= 1
/5
