Which of the following expressions is equivalent to the expression x - (-3)? (A) x - 3
(B) x + (-3)
(C) x + 3
(D) -3x

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

answer: 193

explanation:

200-7 = 193
