x=-15
Step-by-step explanation:
-3x+5(x+2)=4x-(3x+5)
<=>-3x+5x+10=4x-3x-5
<=>-3x+3x+5x-4x=-10-5
<=>x=-15
Ответ:
x=-15/7
Step-by-step explanation:
combine like terms
3x +5x +10=4x-4x+5
distribute
8x+10=4x-3x-5
combine like terms
8x+10=1x-5
subtract 10 from both sides
8x=x-15
subtract x from both sides
8x-x=x-15-x
combine like terms
7x-15
divide both by 7
7x-15
7. 7
x=15
7
