35x it's answer can I help
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

Answer:
x = 3
Step-by-step explanation:
10 + 2(7 - 9x) = 5(2x - 12)
10 + 14 - 18x = 10x - 60
24 - 18x = 10x - 60
+60 +60
-------------------------------------
84 - 18x = 10x
+18x +18x
-------------------------------------
84 = 28x
/28 /28
--------------------------------------
3 = x
