Question 13739: Please help me solve the following problems and can you also show the check? pleeeeeeeeease...thx.
13-(2c+2)=2(c+2)+3c
0.7(3x+6)=1.1-(x+2)
You can put this solution on YOUR website! 13-(2c+2)=2(c+2)+3c
13-2c-2=
-2c+13-2=2c+4+3c
-2c+11=2c+3c+4
-2c+11=5c+4
-2c-5c=4-11
-7c=-7
c=1
Check: Substitute c = 1 to equation
13-(2(1)+2)=2(1+2)+3(1)
13-(2+2)=2(3)+3
13 - 4 = 6 + 3
9 = 9 (Q.E.D)
0.7(3x+6)=1.1-(x+2)-------->multiply with 10
7(3x+6) = 11 - 10x - 20
Check:
0.7(3x+6)=1.1-(x+2) (Q.E.D)
OK
