Which expression is equivalent to 2(c+7)-18x+4/5
mestny [16]

Answer:

2c - 18x + 74/5

Step-by-step explanation:

<u>Step 1:  Distribute </u>

2(c + 7) - 18x + 4/5

(2 * c) + (2 * 7) - 18x + 4/5

<em>2c + 14 - 18x + 4/5 </em>

<u>Step 2:  Combine like terms </u>

2c + 14 - 18x + 4/5

<em>2c - 18x + 74/5 </em>

Answer:  2c - 18x + 74/5

X + 5y - 10 = 0<br> x = 2y - 8
ipn [44]
So since we know what x is, we can substitute it into the original equation for x like so to solve for y...

(2y - 8) + 5y - 10 = 0
2y - 8 + 5y = 10
2y + 5y = 18
7y = 18
y = 18/7 (or about 2.57)

So now we know what x is, we can sub it into the below equation to solve for x...

x = 2(18/7) - 8
x = 36/14 - 8 (or about -5.43)
