To solve for x, you simplify both sides of the equation and then isolate the variable.
<em>10x + 12 = $72.00</em>
<em>x = 6</em>
Six people attended the concert.
<em>Check the answer:
(10 • 6) + 12 = 72.00
60 + 12 = 72.00

<u>Answer: x = 6</u></em>
So negitave 4 times the variable is less than 20.
Answer:
20 - 6c
Step-by-step explanation:
because that shows that 6c is the cost of them and you'd take the cost of them away from how much he payed i guess
They’re supplementary angles, so they’re equal to 180°
2x + 5 + 8x + 5 = 180
10x + 10 = 180
10x = 170
x = 17
