4x +13 = 93-6x. Adding 6x to each side gives:
10x+13 = 93. Subtracting 13 from each side gives:
10x = 80. Dividing both sides by 10 gives:
x = 8.
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
4x+13 = 21 4x = 21-13 4x = 8 x = 2
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
X= -8
x = -6
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
4x+13 = 21 4x = 21-13 4x = 8 x = 2
5x - 4x = 13 - 3 ie x = 10
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
Parallel, the slope of the second equation is 4
4x + 3 = 16 Therefore, 4x = 13 x = 13/4 Therefore, x = 3.25
X= -8
4x - y = 1 3x + y = 13 Simultaneous Equations. Add ; This will eliminate 'y' Hence 7x = 14 x = 2 When x = 2 3(2) + y = 13 6 + y = 13 y = 13 - 6 y = 7 Hence the solution in ( x,y) form is ( 2, 7).
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
x = -6
