y=3x-7
y=-x+1
We're looking for when their x=x and y=y, so set the problems equal to each other.
3x-7=-x+1
3x+x-7=x-x+1
4x-7=1
4x-7+7=1+7
4x=8
4x/4=8/4
x=2
Let x=2 and solve for y in one of the equations.
y=-(2)+1
y=-1
The solution is:(2,-1)
x = 15
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
15x minus 8=minus 180 3x+8=24
An equation where x equals 3.
3x+7=2x-5 x=-12
x = 15
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
15x minus 8=minus 180 3x+8=24
That will depend on what negative something equals which has not been given.
the answer is -3x = 0
An equation where x equals 3.
3x+7=2x-5 x=-12
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
Negative association.
-3x + 5 = 20 -3x = 15 x = -5
2x+3y=13 3x-y=3 x=2
