Solve y=3x+2 7x-4y=7. Find the value of x and y.
Given y= 3x+2. Here in 7x-4y= 7, we can replace y with 3x+2. It will become 7x-4(3x+2)= 7 open bracket by multiplying with 4 7x-(4*3x)+(-4*2)= 7 7x-12x-8= 7 here -4*3= -12 and -4*2= -8. -5x= 7+8 If we take -8 to another side of = it will become +8. x=15/-5= -3 To find y, substitute x in this equation. y= 3*-3 +2 Here put x= -3. = -9+2 = -7 So, x= -3 and y= -7. You solved it!!
