y > 3
Treat the greater than sign [a bit] like an equals sign to solve:
4y - 3 > 9
⇒ 4y > 12 [add 3 to each side]
⇒ y > 3 [divide each side by 4]

An equation.So, for example, all of the following are equations:2 = 22 + 3 = 52x + 3 = 4y - 7For comparison, if the statement contains a less-than or greater-than symbol, it is an inequality, even if it also has an equals sign. Here are some examples:2 + 3 < 72x >= 3y
x + 5 > 10 and x -2 < 1 This results in x > 5 and x < 3 There is no number that is both greater than 5 and less than 3, therefore there is no solution. The thing above is wrong that would make it an "or" statement.
Unfortunately, this website cannot reproduce some crucial mathematical signs. If the equation is 4y = 3, divide each side by 4. y = 3/4 If the equation is 4y + 3 = 0, subtract three from each side, then divide each side by 4. 4y = -3 y = -3/4
4y + 3 >= -94y >= -9 + -34y >= -12y >= -12/4y >= -3
Y=-1
To determine which ordered pair could be a solution to the inequality (4y - 3x - 2 > 0), you can substitute the values of the ordered pair into the inequality. For example, if we take the ordered pair (1, 2), substituting gives (4(2) - 3(1) - 2 = 8 - 3 - 2 = 3), which is greater than 0, thus (1, 2) is a solution. You can test other pairs similarly to find more solutions.
The solution of -6x = -16 is x = 2 2/3, which is greater than -16.
A solution with a pH of 9 has a greater concentration of hydroxide ions than a solution with a pH of 3. The pH scale is a logarithmic scale, with each unit representing a tenfold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has a concentration of hydroxide ions 1,000 times greater than a solution with a pH of 3.
2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.

Add the two equations and get 4x = 12 so x = 3 and y = -1
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
(3 - 4y)(3 + 4y)
Is -3 greater than 3 greater than seven
Move everything except the y to the same side as 12 to put the answer in slope-intercept form. -4y=-3x+12 y=3/4x -3
