Answer:
x=−6
Step-by-step explanation:
<u>Step 1: Simplify both sides of the equation.</u>
3x−7-2/3(9x−6)=15
3x+−7+−6x+4=15(Distribute)
(3x+−6x)+(−7+4)=15(Combine Like Terms)
−3x+−3=15
−3x−3=15
<u>Step 2: Add 3 to both sides.</u>
−3x−3+3=15+3
−3x=18
<u>Step 3: Divide both sides by -3.</u>
−3x/−3=18/−3
x=−6
Answer:
Standard form of a quadratic equation is;
ax^2+bx+c=0
According to the above equations, all of them are in standard form.
Step-by-step explanation:
Answer:
6 runners
Step-by-step explanation:
