Three more than the product of five and a number x?
5x + 3 Example: if x is 8 then 5x + 3 = (5 x 8) + 3 = 40 + 3 = 43
What is 10X plus 43-5X equals 42?
5x + 43 = 42 5x = -1 x = -1/5 Check it. -2 + 43 + 1 = 42 42 = 42 Check.
What is 5x-x equals 48?
-43
How do you do this problem3-2x equals -7x plus 43?
Move all the X elements to one side. 3-2x = -7x+43 (+2x to both sides) 3=-5x+43 Move all the numerical elements to the other side. (-43 to both sides) -40=-5x Divide by -5. 8=x
5x+2y>8 y?
5x+2y>8, y≤4 5x+2(4)>8 5x+8>8 5x>0 x>0

7x 3-2x if x 8?
7x+3-2x= if x=8 5x+3 5(8)+3 40+3 =43
How do you do this problem3-2x equals -7x plus 43?
Move all the X elements to one side. 3-2x = -7x+43 (+2x to both sides) 3=-5x+43 Move all the numerical elements to the other side. (-43 to both sides) -40=-5x Divide by -5. 8=x
5x+2y>8 y?
5x+2y>8, y≤4 5x+2(4)>8 5x+8>8 5x>0 x>0
What is 32-5x equals 3x plus 8?
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
How do you work out 2x plus 43 equals 5x plus 13?
well you first get the 43 and take away 3 to make it 40, then you divide it by 8 to give you 5 so thats how 2x becomes 5x. Then you add 2 x 5 which = 10 then you add the 3 that was taken away from the 40 so you come out with the solution of: 2x + 43 = 5x + 13.
7-5x plus 1?
It is: 8-5x simplified
How do you factor 2x2 plus 5x-12?
2X2+5x-12 4+5x-12 -8+5x 5x-8
What is the answer to 5x 8 equals 23?
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
How do you solve 4x -8 equals 5x?
4x - 8 = 5x 1) Add 8 to both sides. 4x - 8 (+ 8) = 5x (+ 8) Becomes 4x = 5x + 8 2) Subtrate 5x from both sides. 4x (- 5x) = 8 Becomes -1x = 8 Reduced to -x = 8 3) Multiply both sides by -1. Becomes x = -8
