Let's have Steve's age be <em>x</em><em />, and his father's age be <em>f</em>
Then, we can set up equations
Steve is one-fourth as old as his father goes to an equation as x=(1/4)f
In five years (x+5), Steve will be one-third as old as his father will be (f+5). This goes to an equation as x+5=(1/3)(f+5)
We can then solve the first equation for either variable (I will be doing f), and plug it in for a system of equations. 

x=(1/4)f
4x=f ← plug that in for f in the next equation

x+5 = (1/3)(4x+5) ← Solve this for x
3(x+5)=4x+5
3x+15=4x+5
3x+10=4x
10=1x
x=10

Therefore, Steve's age is 10. His father's age is <em>f=4x, </em>plug in 10 for x, and his father's age is 40

The numbers are 15 and 105.
Lin thought a two digit number that is 15, if we multiply 15 with 7 , 15 x 7 = 105 that is we get Jen's number.and if we put 0 between the two digits of Lin's number, we also get Jen's number;that is 105.

-1+|10-8x|=-55...help!!!!
Lunna [17]
Quite simply, this equation has no solution, because an absolute value is never negative (like -55 is negative).  No solution.

Would 2/5x+6/5=y be a proper answer format(i just want to know if it can be =y)
lukranit [14]

yes, it does not matter if the y is at the beginning or at the end. However, most teachers usually prefer to have the y at the beginning as it is easier to read.
