(3)(2)(2)5x=60
12(5x)=60
12(5x)/12=60/12
5x=5
x=1
9x = 60x = 60/9 = 6 2/3 (or 6.67)
65
60/x = 5 60 = 5x x = 12
Algebraically, you're asking to solve for x: 5x - 60 = x4x - 60 = 04x = 60x = 15Let's test just to be sure:15*5 = 7575 - 60 = 15It works, so 15 is the magic number.
15 times 60=900
9x = 60x = 60/9 = 6 2/3 (or 6.67)
( 5 ) ( x ) = 60x = ( 60 ) / ( 5 ) = 12
You cannot solve 1 linear equation in 2 unknown variables. You need at least two independent equations.
5x+10=60 5x=50 5/5=1 50/5=10 So the answer is 10

60/x = 5 60 = 5x x = 12

100 times 0.6 equals 60. This can also be expressed as 100(.06)=60.
Algebraically, you're asking to solve for x: 5x - 60 = x4x - 60 = 04x = 60x = 15Let's test just to be sure:15*5 = 7575 - 60 = 15It works, so 15 is the magic number.
It is 60 times 60 = 3600
15 times 60=900
It is: 60 times 60 = 3600
