Hello!
Let's write this as an equation below.
3x+4=16
We subtract 4 from both sides.
3x=12
Divide both sides by 3
x=4
I hope this helps!
Answer:
x = 14
Step-by-step explanation:
5(22-x)=40
5(22-14)=40
5(22)=110 5(-14)=-70
110-70=40
Answer:
x = - 
Step-by-step explanation:
Given
(x + 5 
) = 
Multiply both sides by 8 to clear the fractions
6(x + 5 ) = 5 ← distribute parenthesis on left side
6x + 33 = 5 ( subtract 33 from both sides )
6x = - 28 ( divide both sides by 6 )
x = 
= -
