8x+15=3x-20 please explain how to solve this

Answers

Answer 1

Answer: 8x + 15 = 3x - 20

First, take away '3x' from both sides.
$8x + 15 - 3x = -20$
Second, subtract '8x - 3x' to get '5x'.
$5x + 15 = -20$
Third, take away '15' from both sides.
$5x = -20 - 15$
Fourth, add '-20 - 15' to get '-35'.
$5x = -35$
Fifth, divide both sides by '5'.
$x = (35)/(5)$
Sixth, how many times does 5 go into 35? 35 ÷ 5 = 7.
$x = -7$

Answer: x = -7

Answer 2

Answer:
You said 8x + 15 = 3x - 20

Subtract 3x from each side: 5x + 15 = - 20

Subtract 15 from each side: 5x = - 35

Divide each side by 5 : x = - 7

can someone explain to me how to use "squared"? I do 2+2 and its four. but when I do 3+3 and I get 6, my brother tells me that's not squared. can you help me out?

Answers

Yes. You've come to the right place. I can help. To "square" a number means to MULTIPLY it by itself . . . NOT add it to itself. '2' is the ONLY number that gives the same result both ways. The square of 3 is 3 times 3 = 9 . The square of 6 is (6 times 6) = 36.
