In equiangular triangle abc ab equals 4x-y bc equals 2x plus 3y and ac equals 7 what are the values of x and y?
Stating that it is an equilateral triangle, we are told that all sides are equal.This is another way of saying:4x - y = 7and2x + 3y = 7So this can be solved by eliminating one of those variables:2x + 3y = 7x = (7 - 3y) / 24((7 - 3y) / 2) - y = 714 - 7y = 7y = 1x = 2
4x plus 7 equals 6x plus -7?
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
What is the answer for 4x plus 7 equals 3?
If 4x + 7 = 3... then x must equal -1
What is 4x minus 7 equals 5 plus 7x?
4x - 7 = 5 + 7x x = -4
What is -3y plus 6 equals 7?
-3y + 6 = 7 Therefore, -3y = 1 Therefore, y = 1/-3 Therefore, y = -0.3 recurring (that is, -0.3333...)
