Assuming A, B and C are angles, it is an obtuse angled triangle.
2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4
4x-2y = 10 -2y = -4x+10 y = 2x-5 which is now in slope-intercept form
Slope intercept form looks like y=mx+b, so we want to get y on on side by itself. -4x+2y=2 Add 4x to both sides: 2y=2+4x Divide both sides by 2: y=1+2x or y=2x+1
no, 4x-3y=11x 3x-5y doesn't equal -11
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
neither
-2x=-4x*24 x=12
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.

4x - 5 + 2x = 37
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x + 2 = 4x -1 2x = 3 x = 1.5
2x = 4x + 3 -2x = 3 x = -3 / 2
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
If 4x-2 equals 2x-34 then x is equal to -16. 4x is equal to 2x-322x is equal to -32x is therefore -16
