Answer:
The operations you see with you eyes are multiplication and addition.
4 times X plus 2 = 10
The operations you don't see are Subtraction and Division.
4x+2=10
Subtract 2 from both sides.
4x+2−2=10−2
4x=8
Divide both sides by 4.
4x/4 = 8/4
x=2
Is there an equation for this?
Step-by-step explanation:
a) 6-9b=3a
First:Subtract
3b=3a
Second: Devide
3b/3a
=(3÷3)(b÷a)
=1b/a
= b/a
B) 6b+2a=3a
First:Transpose (Group the like terms. signs will change.)
-3a+2a=-6b
=-1a=-6b
Second:Divide
=-1a/-6b:(-1÷-6)(a÷b)
=1a/6b
=a/6b
C)a/3=b+2
First: Transpose
a=3+2+b
=a/6+b
