Answer:
.7
Step-by-step explanation:
30/.7 is 21
7x = 42
First, do the inverse operation.
The inverse of multiplication is division.
7x/7 = 42/7
x= 42/7
x= 6
Final answer: x= 6
5n + 4 = 20
5n = 16
n = 16/5 = 3 1/5
I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
<u>-1/2x - 7 = -11</u>
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : <em> x = 8</em>
Take it Allalala !
