Now solve the equation 4(x+3)=8. Remember to: Build the equation on your Equation Mat with algebra tiles. Simplify the equation using your legal moves. Record your work on your paper. Solve for x . That is, find the value of x that makes the equation true.

x=-1

Step-by-step explanation:

4(x+3)=8

4x+12=8

4x=-4

x=-1

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

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
