What is -5-x plus 2-x plus 6-x plus 10-x what is value?
- 5 - x + 2 - x + 6 - x + 10 - x = -5 + 2 + 6 + 10 - x - x - x - x = 13 - 4x
What does (x plus 5)(x plus 6) equal?
(x+5)(x+6) equals x^2 +11x+30
Factorise 2x plus 7 plus 5?
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
Solve x plus 2 divided by 5 equals 6 plus x?
(x+2)/5 = 6+x x+2 = 30+5x x-5x = 30-2 -4x = 28 x = -7
What is the answer to x plus y equals 6 and -x plus 3y equals -2?
x + y = 6 so that -x = y - 6 -x + 3y = -2 that is, y - 6 + 3y = -2 or 4y = 4 or y = 1 and then -x = y - 6 = -5 so that x = 5
What is -5-x plus 2-x plus 6-x plus 10-x what is value?
- 5 - x + 2 - x + 6 - x + 10 - x = -5 + 2 + 6 + 10 - x - x - x - x = 13 - 4x
What does (x plus 5)(x plus 6) equal?
(x+5)(x+6) equals x^2 +11x+30
Factorise 2x plus 7 plus 5?
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
Solve x plus 2 divided by 5 equals 6 plus x?
(x+2)/5 = 6+x x+2 = 30+5x x-5x = 30-2 -4x = 28 x = -7
What is x2-6x plus 5 equals 0?
solving for the x variable given that x2-6x+5=0 factoring the polynomial gives (x-1)(x-5)=0 which leaves you with your two answers, x=1, 5 or you could have used the quadratic equation x = [ -(-6) plus/minus sqrt( (-6)2 - 4*1*5 ) ] / (2*1) x = [ 6 plus/minus sqrt( 36-20 ) ] / 2 x = [ 6 plus/minus 4 ] / 2 x = 3 plus/minus 2 x = 5, 1
What is the answer to 2x plus 3 plus 4x plus 5 equals 6?
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
What is the answer to x plus y equals 6 and -x plus 3y equals -2?
x + y = 6 so that -x = y - 6 -x + 3y = -2 that is, y - 6 + 3y = -2 or 4y = 4 or y = 1 and then -x = y - 6 = -5 so that x = 5
How do you solve 2x2-5x plus 6 when x equals -1?
2x2 - 5x + 6 = ?x = -1(2 x (-1)2) - (5 x -1) + 6 = ?(2 x 1) - (-5) + 6 = ?2 + 5 + 6 = 13
How do you factorize -2xsquared plus 2x plus 60?
-2(x + 5)(x - 6)
What are the possible values for x if x 2 plus 5 x equals 6?
x (x+5) = 6 X equals 1.
What is the number if half of a number increased by 6 is 11?
1/2 x + 6 = 11 1/2 x + 6 - 6 = 11 - 6 1/2 x = 5 2*(1/2 x) = 5*2 x = 10 1/2 of 10 is 5, 5 plus 6 is 11 QED
What is the answer of 5 plus 6 multiplied by 3 minus 2?
31, if the question is (5 + 6) x (3 - 2), 21, if the question is 5 + 6 x 3 - 2.
