Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!
How many times does 24 go into 7?
7 × 1 = 7
7 × 2 = 14
7 × 3 = 217 × 4 = 28
7 goes into 24 only three times, leaving three remainder. So you would write it like this:
3
. 7 goes into 24 three times, there is three left over as remainder, and the denominator from before is 7. Thus the answer.
I do hope this helped :))
27/4
4*6=24
27-24=3
remainder is 3
2 3/4 + 4 3/4
= 6 6/4
= 7 2/4
= 7 1/2
Answer:
2x-25
Explanation:
2(x-4^2)+7
1) Find the exponent
=2(x-16)+7
2) Use the distributive property on the parentheses
=2x-32+7
3) Subtract 32 and 7
=2x-(32-7)
=2x-25
I hope this helps! Please comment if you have any questions.
