5(y-4)=7(2y+1) I need the answer

8_murik_8 [283]

Answer: $y = -3$

Move all terms containing y to the left, all other terms to the right

Add -14y to each side of the equation

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

Combine like terms: 5y + -14y = -9y

$-20 + -9y = 7 + 14y + -14y$

Combine like terms: 14y + -14y = 0

$-20 + -9y = 7 + 0\\-20 + -9y = 7$

Add '20' to each side of the equation

$-20 + 20 + -9y = 7 + 20$

Combine like terms: -20 + 20 = 0

$0 + -9y = 7 + 20\\-9y = 7 + 20$

Combine like terms: 7 + 20 = 27

$-9y = 27$

Divide each side by -9

$-9y/9=27/-9\\y=-3$
