Answer:
Division Property of Equality
Step-by-step explanation:
→In Step 4, it is shown that the equation is:
3x = 30
→However, to solve for x, you must get it by itself. This means you need to get rid of the 3 that's being multiplied. So since the 3 is being multiplied to x, you must do the opposite of multiplication, which is division.
→As you can see, the total of 30 is decreased in Step 5, since it has been divided by 3, giving you a total of 10.
This shows that the property of equality that yields Step 5 is the <u>Division Property of Equality.</u>
Answer:
x=-2
y= 8
Step-by-step explanation:
Given data
10x – 2y = -36-----------1
7x – 2y = -30--------------2
-Subtract to eliminate y
3x-0= -6
3x= -6
x= -6/3
x= -2
Put x= -2 in
7(-2)– 2y = -30
-14-2y=-30
-14+30=2y
16=2y
y= 16/2
y= 8

4 |-8| = 4*8 = 32
4 |<span>8</span>| = 4*8 = 32
Answer:
Hi
Step-by-step explanation:
You have to subtract it because you add a negative and positive fraction together you can add a positive with a positive or vice versa but you can add n and p together so you have to subtract.
Hope it helps
