How would I solve this equation?
d-1 = -1 1
____ ___
4 2
(d-1) divided by 4 = -1 and 1/2
Thanks,
Ok, I'll set up your problem this way:
(d-1)/4 = -1 1/2
-1 1/2 is the same as -3/2.
Therefore: (d-1)/4 = -3/2
Multiply each fraction by a common denominator, which is 4:
4 [ (d-1)/4 = -3/2 ]
Simplifying:
d - 1 = -6
d = -5
Substitute -5 for d in the original equation to check. It always helps to check your work!
I hope this helps.
d= -4
3/2
d[1/4]=1/3
5/8x+3/5=8
To solve the equation (d-1)/4 = -3/2, you can follow these steps:
1. Rewrite -1 1/2 as an improper fraction. To do this, multiply the whole number (-1) by the denominator (2), and then add the numerator (1). This gives you -3/2.
2. Now, you have the equation (d-1)/4 = -3/2.
3. Multiply both sides of the equation by the denominator of the fraction on the left side (4) to get rid of the fraction. This gives you (d-1) = -3/2 * 4.
4. Simplify the right side of the equation (-3/2 * 4) by multiplying the numerators and multiplying the denominators separately. This gives you (d-1) = -12/2.
5. Simplify further by dividing the numerator (-12) by the denominator (2). This gives you (d-1) = -6.
6. To isolate the variable "d," add 1 to both sides of the equation. This gives you d = -6 + 1.
7. Simplify the right side of the equation (-6 + 1) to get the final answer: d = -5.
8. To verify your solution, substitute -5 for d in the original equation [(d-1)/4 = -3/2]. You should get (-5-1)/4 = -3/2, which simplifies to -6/4 = -3/2, and further simplifies to -3/2 = -3/2.
So, the solution to the equation (d-1)/4 = -3/2 is d = -5.
