What is the answer to 2x plus 3 equals 4x-7?
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x

Convert 2x-3y equals 7 to slope intercept form?
If 2x - 3y = 7, -3 y = 7 - 2x or y = (2x - 7)/3, or y = (2/3)x - (7/3). The slope is 2/3 and the y-intercept is -(7/3).
Each of the numbers below is a solution of the inequality 2x plus 3 greater than 7 except A 3 B 6 C 1 D 5?
