If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
3 x 3 + 4 x 8 = 9 + 32 ...
-x + 4y = 8
x = -5/3 y = -4/3
How do you solve 4y plus x equals 8
1
If x=2, then 7x = 14 and if y=5 then 4y=20.
Put in this form to see. Y = mX + c 3X - 4Y = - 3 - 4Y = - 3X - 3 Y = (3/4)X + 3/4 --------------------- 8X + 6Y = 14 6Y = - 8X + 14 Y = (- 4/3)X + 7/3 ----------------------- Closer to perpendicular than anywhere near parallel!
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
3 x 3 + 4 x 8 = 9 + 32 ...
x=4y+1 x=4y-1 No,they have different solutions.
3x=4y-x 4x=4y x=y
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
x equals -3, and y equals 1.
-x + 4y = 8
x = -5/3 y = -4/3
