What is the value of x in the equation 3 minus 2 x = negative 1.5 x? –6 –2 2 6
olga_2 [115]

Answer:

x=118.25

Step-by-step explanation:

3−2x=−1.5−6−226

3+−2x=−1.5+−6+−226

−2x+3=(−1.5+−6+−226)(Combine Like Terms)

−2x+3=−233.5

−2x+3=−233.5

Step 2: Subtract 3 from both sides.

−2x+3−3=−233.5−3

−2x=−236.5

Step 3: Divide both sides by -2.

−2x

−2

=

−236.5

−2

x=118.25
