<h3><u>Solution:</u></h3>

Ken earned $176 from his part-time job this summer

Amount earned = $ 176

He spent 25% of his money on games

Therefore,

Money spent on games = 176 - 25 % of 176

$\text{Money spent on games } = 176 - \frac{25}{100} \times 176\\\\\text{Money spent on games } = 176 - 0.25 \times 176\\\\\text{Money spent on games } = 176 - 44\\\\\text{Money spent on games } = 132$

He is going to donate 1/4 of the remaining money to charity

Reamining amount = 176 - 132 = 44

Therefore,

$Money\ given\ to\ charity = \frac{1}{4} \times 44 = 11$

Thus he gave $ 11 to charity

Solve for x: 6x – 8y = 12

Tcecarenko [31]

Hi there!

Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.

$6x + 8y = 12$

Step 1) Add 8y to both sides.

$6x - 8y + 8y = 12 + 8y 6x = 8y + 12$

Step 2) Divide both sides by 6.

$\frac{6x}{6} = \frac{8y + 12}{6}$

$x = \frac{4}{3} y + 2$

Final Answer -

$x = \frac{4}{3} y + 2$

Hope this helps! :D
