Answer:
x<5
Step-by-step explanation:
the greater sign will firstly be changed to = for better solving so we obtain
3+9x=4(x+7)by opening bracket
3+9x=4x+28
9x-4x=28-3
5x=25
divide all through by 5x
we obtain
x=5
the greater sign change here
which is x<5
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
