Divide the two members of equation by 12
Answer:
Since 16.5 is negative, the only way to get that answer is to multiply 5 by something to negative(x)
Step-by-step explanation:
Answer:
x=-20
Step-by-step explanation:
3x+178=6x+238
-3x=60
x=-20
19x-53 / x^2 + x + 2
You want to put a - ( 19 x / x^2 + x + 2 - 53/x^2 +x +2)
Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90

-30 -30
a = -3
