yes is 3(x+5) over 5. sorry i put it weird

3x + 15 = 10x - 10
25 = 7x
x = 25 / 7

3(x + 5) / 5 = 2x - 2
3x + 15 = 10x - 10
7x = 25
x = 25/7
Answer: x = 25/7 or 3 4/7
Proof:
3(25/7 + 5) / 5 = 2(25/7) - 2
(75/7 + 15) / 5 = 50/7 - 2
15/7 + 3 = 50/7 - 14/7
15/7 + 21/7 = 36/7
36/7 = 36/7

[3(x+5)]/5 = 2x-2
3(x+5) = 10x - 10
3x + 15 = 10x -10
7x = 25
x = 25/7 = 3 4/7

Multiply both sides by 5. This gets rid of the fraction. Then distribute the 3 on the left so that you have 3x + 15 = 10x - 10. Now combine like terms and get x by itself.

multiply both sides by 5...
3(x+5)=10x-10
3x+15=10x-10
15+10=10x-3x
25 = 7x
x = 25/7

All answer are incorrect or partially ideal! The is a try no count if the equation holds. via fact the quotient x/x is given, the equation is defined for x=0, via fact the actuality, that there is a real shrink for x goint to 0 of x/x: limit_x->0 x/x=one million. So do away with the quotient a minimum of for x unequal 0. The equation now could be x+x²=x². This equation could be rearranged via unique arithmetic operations. It supplies x=0. stupid or. What does is mean? The equation would not carry for x unequal 0. it rather is it. it could returned be simplified one million+x=x or one million=0, that's erroneous. For 0 is holds interior the secure form and interior the shrink attention: 0/0+0=one million+0 unequal 0. The equation would not be valid for any genuine numbers!

I don't understand the question if it is
3(x+5)=2x-2 Then
3x+15=2x-2
3x-2x=-2-15
x=-17

multiply both sides by 5...
3(x+5)=10x-10
3x+15=10x-10
15+10=10x-3x
25 = 7x
x = 25/7
EASY !!!!!!
