2x+3<7 2x<7-3 2x<4 x<2
Since 2x + 3 > 7, then 2x > 4. and x > 2.Of the choices listed, only 0 is not greater than 2.Steps.2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2
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

2x+3 = 7 2x = 7-3 2x = 4 x = 2
2x+3<7 2x<7-3 2x<4 x<2
The inequality with the terms 2x, 3 and 7 can be written as 2x -3 = 7, 2x + 3 = 7, 2x * 3 = 7, and 2x/3 = 7. This means that the solutions are 5, 2, 7/4, and 21/2 respectively.
Since 2x + 3 > 7, then 2x > 4. and x > 2.Of the choices listed, only 0 is not greater than 2.Steps.2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2
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
2x+3 = 7 2x = 7-3 2x = 4 x = 2

2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
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).
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
2x 5 -7 = 3
Expanding the brackets: 6x+21 = 3(2x+7)
7 and 3 - 2x are factors of 21 - 14x
