What else can I help you with?
4x plus 6y equals 62 and -6x plus 6y equals -18?
4x+6y=62 -6x+6y=-18 what is the ordered pair
8x plus 30 equals 4x plus 18 solve for x?
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
8x plus 30 equals 4x plus 18?
subtracting gives 4x = -12 so x = -3
5x-18 equals 4x plus 7?
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
6-2x equals 4x plus 18?
x=4
What is the answer to 5x-18 equals 4x plus 4?
Given: 5X - 18 = 4X + 4; subtracting 4X from each side: X - 18 = 4; adding 18 to each side, X = 22
-y equals 4x plus 1 4x plus y equals 2?
2
4x plus 5 equals -19 equals?
4x-14
13 equals negative 4x plus 9?
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
4 x plus 4 plus 14 equals 54?
4x + 4 + 14 = 54 4x + 18 = 54 4x = 54 - 18 4x = 36 x = 36/4 x = 9 Check: 4(9) + 4 + 14 = 54 36 + 18 = 54 54 = 54
What is 4x plus 7 plus 3x equals 19 plus x?
4x plus 7 plus 3x equals 19 plus xx = 2
4x plus 5y equals 51 4x - 5y equals 21?
Simultaneous Equations. 4x + 5y = 51 4x - 5y = 21 eliminate 'y' by addition. Hence 8x = 72 x = 72/8 x = 9 When x = 9 Substitute into eith equation. 4(9) + 5y = 51 36 + 5y = 51 5y = 51 - 36 5y = 15 y = 3 Hence the answer is ( x,y) = ( 9,3).
