2x-y equals 10 3x-2y equals 8?
Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.
What is the solution of x 8 -12?
20
How do you solve for x if the problem is 3x plus 20?
You haven't given the solution to the equation ! 3x + 20 = ? If you have the number for the question-mark - you can find the value of x ! For example in the equation 3x + 20 = 50... the value of x is 10.
How do you solve the equation -3x minus 5 equals -20?
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
How would you evaluate the expression 3x 4y equals 9 when x equals 2 and y equals 5?
3x + 4y = 9 is an equation, a statement that states the two expressions 3x + 4y and 9 are equal. We like to know if there are any values of the variables x and y that will make the statement a true one. In our case, we're going to check if x = 2 and y = 5, will satisfy the given equation. In other words, if we substitute the corresponding values of x and y into the equation and the left side will equal to the right side, then (2, 5) is a solution. Otherwise, it's not. Check: 3x + 4y = 9; x = 2 and y = 5 3(2) + 4(5) =? 9 6 + 20 =? 9 26 = 9 False Therefore, (2, 5) is not a solution.
How to make an equation equaling six or three.?
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
Does the equation 4x equals -20 have a solution over the set of rational numbers?
Yes, it does.
What is the solution to x minus 14 equals 20?
x = 34 {add 14 to both sides: x - 14 + 14 = 20 + 14 = 34}
How do you Find the solution for the equation 6 - 2x equals 20?
First you get the variables on one side and the constants on the other. -2x = 14 Then you divide by -2 to get the variable alone. x = -7
Help me solve this equation by substitution. x-5y equals 10 2x-10y equals 20?
what is the solution of x-5y=10 and 2x-10y=20
What is the solution to this equation -20x equals -300?
280
What is y plus x minus 20 equals 3?
One equation y equals 9 x equals 14 Don't forget to add it to 23.
What is the solution to 4x minus 14 plus 6 equals 12?
4x - 14 + 6 = 12 first I would combine the terms -14 and +6, which when added together give us -8, so 4x - 8 = 12 then I would add 8 to both sides of the equation, which gives us 4x = 20 then I would divide both sides of the equation by 4, which gives x = 5 and that is the solution.
2x-y equals 10 3x-2y equals 8?
Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.
How do you solve 3X plus 6 equals x plus 20?
balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7
