What is 2d plus 7 equals 9?
2d + 7 = 9 2d = 2 d = 1
What is the answer to 2d plus 7 equals 9?
To keep it balanced, whatever you do to one side of the equals, do to the other: 2d + 7 = 9 ⇒ 2d + 7 - 7 = 9 - 7 ⇒ 2d = 2 ⇒ 2d ÷ 2 = 2 ÷ 2 ⇒ d = 1
What is 2d-8 equals 10?
everyone today you will be learning how to solve the equation 2d-8=10. so first you need to add 2 by 10 which is 12. then you subtract 12 by 8 and get 4. and that's your answer. now how easy was that?!!!
What is d in this equation 7d-12 plus 2d plus 3 equals 18?
7d - 12 + 2d + 3 = 18Group the like terms for d on the left side. Move the integers to the right side remembering to reverse their signs (positive/negative)7d + 2d = 18 + 12 - 3Which becomes:9d = 27Divide each side by 9:d = 3
What is the answer to 2d plus 25 equals 55?
2d + 25 = 55Therefore 55 - 25 = 2dTherefore, 2d = 30d = 30/2Therefore, d = 15
What is 2d plus 1 equals 29 equal?
2d+1=29 2d=29-1=28 d=28/2=14
How do you solve 3d plus 8 equals 2d-7?
3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
Solving 3d plus 8 equals 2d-7?
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
What is -7d equals 50 plus 2d?
-7d = 50 + 2d -9d = 50 d = -50/9 Or about -5.6
