What is the value of x

x = 20

Step-by-step explanation:

Tangents to a circle from an external point are congruent, so

2x - 5 = x + 15 ( subtract x from both sides )

x - 5 = 15 ( add 5 to both sides )

x = 20

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
