Answer:
<u>~Senpi boi here~</u>
Step-by-step explanation:
Multiply all terms by x and cancel:
x+2x+1=1x
3x+1=x(Simplify both sides of the equation)
3x+1−x=x−x(Subtract x from both sides)
2x+1=0
2x+1−1=0−1(Subtract 1 from both sides)
2x=−1
2x
2
=
−1
2
(Divide both sides by 2)
x=
−1
2

Answer:
1
Step-by-step explanation:
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751
