How do you solve and inequality with two signs?
Split it into two parts, solve each part as if it had an "=" sign instead of an inequality. Ex: -6<3x+2<12 -6<3x+2; -8<3x; -8/3<x Other side-- 3x+2<12; 3x<10; x<10/3 Then put them back together. -8/3<x<10/3 *Make sure you remember to switch the direction of the inequality symbol if you are dividing by a negative number.*
How do you solve an inequality when using the distributive property?
You solve an inequality in the same way as you would solve an equality (equation). The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign. Thus, if you have -3x < 9 to find x, you need to divide by -3. That is a negative number so -3x/(-3) > 9/(-3) reverse inequality x > -3
Solve the following inequality 38 4x3 plus 7-3x?
To solve the above inequality equation it has to have an equality sign so that i group all the the knowns and the unknowns.
How do you solve this equation 3x plus 2y equals 12 solve for y?
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
How do you solve 3x equals 12?
3x=12 3x/3=12/3 x=4
What is a double inequality?
A double inequality is an inequality where there are two signs, as opposed to one.Ex: an inequality could be 3x < 15A double inequality could be 3x < 15 < x + 20If you'd want to solve that double inequality, you split it into to expressions:3x < 15 and x + 20 > 15Then just solve.x < 5 and x > -5-5 < x < 5
How do you solve for y 3x-y equals 12?
-9
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
How do you solve 7x plus 3 divided by 3x minus 7?
The question contains an expression but not an equation or inequality. There is, therefore, nothing to solve!
How do you solve 7x plus 12 equals 3x?
7x = 3x - 12 4x=-12 x=-3
How do you solve 3x-7?
10
How can you solve this inequality 5-3x equals 17?
5 - 3x = 17 is not an inequality, it is an equation. Inequalities never have equal signs in them, only "less/greater than", and "less/greater than or equal to" signs.To solve the equation:Step 1: Add 3x to both sides: 5 = 17 + 3xStep 2: Subtract 17 from both sides: -12 = 3xStep 3: Divide both sides by 3: x = -4The solution to the equation is x = -4
