1_Resuelvan y verifiquen las siguientes ecuaciones A/ 2x+13=-15
B/ x+3x+5=-3.5
C/-4x+2x-7=-x+14+2x-54:(-9)
D/8x-6+x+8=-31+3x-7

2_aplicar la propiedad distributiva en las siguientes ecuaciones y verificar los resultados obtenidos,
A/ 9.(x+5)=45
B/ 4.(x-5)+16=16+5.(x-2)
C/(12x-20):4=-2x

AYUDAAA PORFA

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

could you provide figure.
