5(y-4)=7(2y+1)<br>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

<u>Add -14y to each side of the equation</u>

<u></u> $-20 + 5y + -14y = 7 + 14y + -14y$ <u></u>

<u></u>

<u>Combine like terms: 5y + -14y = -9y </u>

<u></u> $-20 + -9y = 7 + 14y + -14y$ <u></u>

<u></u>

<u>Combine like terms: 14y + -14y = 0 </u>

<u></u> $-20 + -9y = 7 + 0\\-20 + -9y = 7$ <u></u>

<u></u>

<u>Add '20' to each side of the equation</u>

<u></u> $-20 + 20 + -9y = 7 + 20$ <u></u>

<u></u>

<u>Combine like terms: -20 + 20 = 0 </u>

<u></u> $0 + -9y = 7 + 20\\-9y = 7 + 20$ <u></u>

<u></u>

<u>Combine like terms: 7 + 20 = 27 </u>

<u></u> $-9y = 27$ <u></u>

<u></u>

<u>Divide each side by -9</u>

<u></u> $-9y/9=27/-9\\y=-3$ <u></u>
