If I multiply a number by 4 and then add 8 the total is 32 .What is the number ?
4
6
8
none of these
Solve 7/x + 8/y = 2 and 2/x +12/y = 20
x = 3/2 and y = 1/2
x = -1/2 and y = 1/2
x=5/4 and y = 1/3
x = 3/4 and y = 2/3
If (x-5)/4 = 3.then the value of x is ___________ .
7
17
12
-7
x + y = 5
x - y = 7 , the solution of the equation is x - y = 7 .
x = -1 , y = 6
x = 6 , y = -1
x = 3,y = -2
x = -2 ,y = 3
