using the t-table determine 3 solutions to this equation: y equals 2x
This is an equation of a line. There are an infinite number of solutions which are all points on the line. It is a linear equation.
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
2x must equal 12 so x is 6.
To solve for x in the equation 2x - 17 = 13, you first need to isolate the variable x. Add 17 to both sides of the equation to get 2x = 30. Then, divide both sides by 2 to find x = 15.
2x3 + 4 = 17 2x3 = 13 x3 = 13 / 2 x = (13 / 2)1/3 x = 521/3 / 2
2x+17=6x-23 23+17=6x-2x 40=4x x=40 / 4 therefore x=10
