5x+3y
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
If: 4x = x+15 Then: x = 5
(A): 4x + y = 7 (B): 2x - 3y = -7 2*(B) 4x - 6y = -14 Subtract from (A) 7y = 21 Divide both sides by 7: y = 3 Substitute in (A): 4x + 3 = 7 ie 4x = 4 or x = 1 Answer: x = 1 , y = 3
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
yes
5x+3y
-4x + 3y = 9
3y = 4x + 9 -4x + 3y = 9 is the standard form
3y=4x+9.....-4xAnswer: 4x-3y=9
4x + 3y=9 x=0 y=3
(1) x+y=15(2) 4x+3y=38From (1) one gets x=15 -y, put into(2)4(15-y)+3y=3860-4y+3y=3860-y=38y=22 then x=15-y=-7(-7,22) is the solution
4x+3y = 12 3y = -4x+12 y = -4/3x+4
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
x+y=15, or y=15-x4x+3y=38Substitute y in 2nd equation with 15-x:4x+45-3x=38x=-7y=15-(-7)=22(-7,22)
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
x = 3 and y = 0
