Answer:
5 1/3 x+8 1/2 =3 1/3 ?
the correct answer is -1.774
Step-by-step explanation:
51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule
so we have,[ 51/3] x + 81/2 =31/3
we have 51x/3 + 81/2=31/3
we collect the like terms;
51x/3= 31/3- 81/2
finding the lcm
51x/3= 2[31} - 3{81}/6
51x/3= 62-243/6
51x/3= -181\6
by using cross multiplication
we have;
6{51x}= 3{-181}
306x = -543
divide both sides by 306
we have;
x = - 1.774
check your answer from
306x=-543
306{-1.774}= -543
-543= -543
Answer:
You would multiply the x component by -2
Step-by-step explanation:
(-2) (-2x-5y)=-2(-1)
4x+10y=2
4x+2y=8
set both equal to 4x
4x=2-10y
4x=8-2y
2-10y=8-2y
-6=8y
y=-6/8
y=-3/4
4x + 2(-3/4) = 8
4x=38/4
x=38/16
x=19/8
