Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
4x+5y = 30 5y = -4x+30 y = -4/5x+6 in slope intercept form So the y intercept is 6.
y = 4x-3
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
Alright this is not very well put, so I have three possible equations that I can think of on the fly. I will attempt to answer all three.1) (4)5x-y=+y +y(4)5x=y/4 /45x=y/4/5 /5[x=(y/4)/5]2) (4x)5x-y=20x2-y=+y +y20x2=y/20 /20[x2=y/20]3) 4x=5x-y+y +y4x+y=5x-4x -4x[y=x]1) (4)5x-y=+y +y[20x=y]2) (4x)5x-y=20x2-y=+y +y[20x2=y]3) 4x=5x-y+y +y4x+y=5x-4x -4x[y=x]
-3
4x-y
IF 5x+3y=-9 you would subtract 5x on both sides so you would then have 3y=-5x-9 then you would divide by 3 on both sides so your answer would be y=-5/3x-3
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
-x+ 4y>-8, x+y≤3 y≤3-x -x+4(3-x)>-8 -x+12-4x>-8 12-5x>-8 -5x>-20 x>4 y≤3-(4) y≤-1
5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
4y=-5x-12 your slope would be -5/4 your new slope intercept form would be y=-5/4x-3
4x-y+3 = 0 -y = -4x-3 y = 4x+3 Therefore: the slope is 4 and the y intercept is 3
So substitute for y : x + 4x = 5 so 5x = 5, so x=1, y=4
