If yo have |a|=b solve for a such that a=b or a=-b
divideboth sides by 2
|x|=3/2
x=3/2 or -3/2
Answer:
x=0,y=-3
Step-by-step explanation:
3x-5y=15 - equation(1)
x-4y=12 => x=12+4y -equation (2)
Replace equation (2) in equation (1)
3(12+4y)-5y=15
36+12y-5y=15
7y=15-36
7y= -21
y = -21/7
y=-3
If y=-3,then replace in equation (1) ; 3x -5(-3)=15
3x+15=15
3x=0
x=0
Answer:
it has no solution.......
answer will be 3x+4 = 3x+4 i.e, 0=0 ,so
but if 3x+4 = 0 , x= -4/3 . Its a linear equation and has only one solution
I believe that x = 2 and y = -2
