1. 1/23
2. -10/17
3. -1 1/4
# 3 is right.
The first two are wrong.
how do u solve it
15j-10+8=11
15j = 11 + 10 - 8
15j = 21 - 8
j = 13/15
Your second problem is correct. I'm sorry, but I misread it the first time.
Sure! Let's solve these three equations step by step:
1. 1.15j - 10 + 8 = 11
To solve this equation, we need to isolate the variable j. To do so, we will combine the constant terms on one side and the variable terms on the other side of the equation.
-10 + 8 = 11 - 1.15j
Simplifying the left side gives us:
-2 = 11 - 1.15j
Next, we want to isolate the variable j by moving the -1.15j term to the other side of the equation:
-1.15j = -2 - 11
Simplifying the right side gives:
-1.15j = -13
Finally, we can solve for j by dividing both sides of the equation by -1.15:
j = -13 / -1.15
j ≈ 11.3
So the solution for j is approximately 11.3.
2. 18m - 6 - m = -16
To solve this equation, we will first combine the m terms on the left side and combine the constant terms on the right side.
18m - m - 6 = -16
Combine the m terms:
17m - 6 = -16
Next, we will move the -6 term to the right side of the equation:
17m = -16 + 6
Simplifying the right side gives us:
17m = -10
Finally, we can solve for m by dividing both sides of the equation by 17:
m = -10 / 17
m ≈ -0.588
So the solution for m is approximately -0.588.
3. 18m - 6m - 1 = -16
To solve this equation, we will combine the terms involving m on the left side and combine the constant terms on the right side.
18m - 6m - 1 = -16
Combine the m terms:
12m - 1 = -16
Next, we will move the -1 term to the right side of the equation:
12m = -16 + 1
Simplifying the right side gives us:
12m = -15
Finally, we can solve for m by dividing both sides of the equation by 12:
m = -15 / 12
m = -1.25
So the solution for m is -1.25.
