4 ( x + 5 ) = x + 8
4 * x + 4 * 5 = x + 8
4 x + 20 = x + 8
4 x - x = 8 - 20
3 x = -12
x = -12 / 3
x = - 4
hope this helps!
Answer:
Step-by-step explanation:
7x - 6 = 12 - 2x
9x - 6 = 12
9x = 18
x = 2
7(2) - 6 = 14 - 6 = 8 AB
12 - 2(2) = 12 - 4 = 8 BC
8 + 8 = 16 AC
Answer:
x = 
Step-by-step explanation:
Given
=
( cross- multiply )
25 × 2x = 5 × 4
50x = 20 ( divide both sides by 50 )
x =
= 
Answer:
(x+8) ^2=64
Step-by-step explanation:
that will give you your two solutions: x= -16 and x=0. I hope this helps!!!
