Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7

Answer:
y=10.4
Step-by-step explanation:
If you mean Y instead of x then the answer is 10.4
3.8+y=14.2
-3.8 -3.8
y=10.4

Step-by-step explanation:
<u>Step 1: Define</u>
3 - 4r ≥ 15
<u>Step 2: Solve for </u><em><u>r</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
- [Division Property of Equality] Divide -4 on both sides: r ≤ -3
<u>Step 3: Compare</u>
- Substitute in <em>r</em>: -3 ≤ -3
This is true. -3 is less than <em>or equal to</em> -3.
