Hi Brainiac

Distribute

(5)(y)+(5)(-4)=(7)(2y)+(7)(1)

5y-20=14y+7

Now we need to subtract 14y from both sides

5y-20-14y=14y+7-14y

-9y-20=7

Now add 20

-9y-20+20=7+20

-9y=27

Divide both sides by -9 to both sides so we can find the value for y

-9y/-9= 27/-9

y= -3


I hope that's help:0

-8= 3-5(x+6) solving algebraicaily​
SOVA2 [1]

Let's solve your equation step by step

-8=3-5(x+6)

Step 1: simplify both sides of the equation

-8=3-5(x+6)

-8=3+(-5)(x)+(-5(6) (distribute)

-8=3+-5x+-30

-8=(-5x)+(3+-30) (combine like terms)

-8=-5x+-27

-8=-5x-27

Step 2: flip the equation

-5x-27=-8

Step 3: add 27 to both sides

-5x-27+27=-8+27

-5x=19

Step 4: Divide both sides by -5

-5x/-5 = 19/-5

Answer : x= -19/5
