ALGEBRAIC EQUATIONS REVIEW
a. x+10=6
-10 -10
subtract 10 from both sides.
x=-4
b. x/3=18
to get x by itself multiply 3 on both sides
(x/3)=18(3)
x=54
c. 2x+y=13, y=3
plug in the given y
2x+3=13
subtract 3 from both sides
2x=10
dive both side by 2
x=5
d. A=C/ X
multiple both sides by X
X(a)=(C/X)X
XA=C
divide both sides by A
X=C/A
e. F=9(d/x^2), F=3, d=12
plug in the variables
3=9(12/x^2)
distribute 9 and multiply
3=108/x^2
3x^2=108
divide by 3 on both sides
x^2=36
find square root
x=6
