Answer:

Step-by-step explanation:

<u>2x + 3x</u> - 10 = 90

Combine like terms

5x - 10 = 90

Add 10  to both sides

5x = 90+10

5x = 100

Divide both sides by 5

x =100/5

x = 20

The LCM of two numbers is 60. Their GCf is 6 and their difference is 18. What are the two numbers?
Aliun [14]
LCM(x,y)=60\\&#10;GCF(x,y)=6\\&#10;x-y=18\\\\&#10;LCM(x,y)=\dfrac{|x\cdot y|}{GCD(x,y)}\\&#10;60=\dfrac{|x\cdot y|}{6}\\&#10;|x\cdot y|=360\\\\\\&#10;|x\cdot y|=360\\&#10;x-y=18\\\\&#10;|x\cdot y|=360\\&#10;x=18+y\\\\&#10;|(18+y)\cdot y|=360\\&#10;|18y+y^2|=360\\&#10;18y+y^2=360 \vee 18y+y^2=-360\\&#10;y^2+18y+81=441 \vee y^2+18y+81=-279\\&#10;(y+9)^2=441 \vee (y+9)^2=-279\\&#10;y+9=\sqrt{441} \vee y+9=-\sqrt{441}\\&#10;y=21-9 \vee y=-21-9\\&#10;y=12 \vee y=-30\\\\&#10;x-12=18 \vee x-(-30)=18\\&#10;x=30 \vee x=-12\\\\&#10;\boxed{x=30, y=12 \vee x=-12, y=-30}
