Best ResponseYou've already chosen the best response.2you can either solve the system or plug in the given values to see if they fit eg for first one y = 22 8x  2 = 8(3)  2 = 24  2 = 22 they both come to same value so thay fit for first equation Now try the same values for y = 6x + 4 and see if they fit

Best ResponseYou've already chosen the best response.0could you help me with this one how many solutions does the system have ? 12y=3x+20 y=1/4x+5/3

Best ResponseYou've already chosen the best response.2yw pooja195 's method was quicker than mine though as both 6x+4 and 8x  2 are equal to y they are equal to each other so you only needed to plug x = 3 into his equation to see if LHS = RHS

Best ResponseYou've already chosen the best response.2the way to do these is to multiply one equation by a number so that the terms in y or x have the same coefficient ( the coefficient is the number in front of the x or y)

Best ResponseYou've already chosen the best response.2so as we have 12y in equation 1 and y in equation 2 we multiply the second one by 12 equation 1 12y =  3x + 20 equation 2 12y = 3x + 20  the same equation so how many solution s does this have?

Best ResponseYou've already chosen the best response.2No  Hint; you can put any value of x into the equation and work out a value of y  in fact many many values of x...
