14X=63 DIVIDE BOTH SIDES BY 14 & WE GET
14X/14=63/14 OR
X=4.5 ANSWER
PROOF
14*4.5=63
63=63
--------------------------------------------------
-4.5X=18.6
X=18.6/-4.5
X=-14.133333 ANSWER
PROOF
-4.5*-4.1 1/3=18.6
18.45-4.5*-1/3=18.6
18.45+.15=18.6
18.6=18.6
----------------------------------------------
8=6+3X
3X=8-6
3X=2
X=2/3 ANSWER
PROOF
8=6+3*.66666
8=6+2
8=8
---------------------------------------------------------
5(X-7)=29
5X-35=29
5X=29+35
5X=64
X=64/5
X=12.8 ANSWER
PROOF
5(12 4/5-7)=29
60+4-35=29
64-35=29
29=29
-----------------------------------------------------------
3(X-5)+8=12
3X-15+8=12
3X=12-8+15
3X=19
X=19/3
X=6.333333 ANSWER
PROOF
3(6 1/3-5)+8=12
18+1-15+8=12
27-15=12
12=12
