Answer:
<em><u>x = 249</u></em>
Step-by-step explanation:
Step 1. Combine like terms
1/3x + 166 = x
Step 2. Subtract 1/3x from both sides
166 = 2/3x
Step 3. Multiply it all by 3/2 to get rid of the 2/3
249 = X
x=249
1/3 x -5 +171 =x
Combine like terms
1/3x +166 = x
Subtract 1/3x from each side
1/3x -1/3x +166 = x - 1/3x
166 = x-1/3x
Get a common denominator for the right
166 =3/3x -1/3x
166 = 2/3 x
Multiply by 3/2 To isolate x
166 * 3/2 = 2/3 x*3/2
249 =x
x = 4
used a calculator i hope this helps <3
∣2x+7∣ for x=-4
Use the substitution method
∣2*-4+7∣
Mutiply first then add +7
∣2*-4∣= -8
∣-8+7∣= -1
Whenever there is a negative number for absolute value , the number becomes a + positive number.
∣-1∣= 1
1
