3(x-7)=x+11
3x-21=x+11
3x=x+11+21
3x=x+32
3x-x=32
2x=32
x=32/2
x=16
Answer:
5. 40
Step-by-step explanation:
(14) +(4x+6) = 8x
14 + 4x+ 6 = 8x
20 = 8x - 4x
4x = 20
x = 5
RT = 8x
= 8 * 5....since x = 5
= 40
You will have to figure out the last equation but here is the rest:
The value of 6 in 372,645 is 600.
Hope it helps!!!!
[ Answer ]
Y = -12 / 5
[ Explanation ]
Expand:
-3y - 9 = 2y + 3
Add 9 to both sides:
-3y - 9 + 9 = 2y + 3 - 9
Simplify:
-3y = 2y + 12
Subtract 2y from both sides:
-3y - 2y = 2y + 12 - 2y
Simplify:
-5y = 12
Divide both sides by -5:
-5y / -5 = 12 / -5
Simplify:
Y = -12 / 5
