-3(3x=15)-(10=x)=35

OpenStudy (anonymous):

ummm... Did you type that incorrectly?

OpenStudy (anonymous):

yes its -3x+15)-(10+x)=35

OpenStudy (anonymous):

Ah ok

OpenStudy (anonymous):

so its (-3x+15)-(10+x)=35?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Ok Taking everything out of the parentheses... -3x + 15 -10-x = 35 <-------- Distributive Property -4x +5 = 35 <----- Commutative Property -5 -5 ------------- -4x = 30 /-4 /-4 ------------ x = -7.5 or -15/2
