Answer:

4x - y = -3y = 5x

Write as a system

4x-y = 5x

-3y = 5x

Simplify the expressions

-x-y = 0

-5x-3y = 0

Multiply both sided by -5

5x + 5y = 0

-5x - 3y = 0

2y = 0

y = 0

Substitute the value of y into the equation

-x-0= 0

x=0

A possible solution is (x,y) = (0,0)

Step by step how to factor:<br> 2y^2+9y+9=0

weeeeeb [17]

Use ac method
for ax²+bx+c=0 when a≠1

multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b

2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that

2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero

y+3=0
y=-3

2y+3=0
2y=-3
y=-3/2

y=-3 and -3/2
it's factored form is (x+3)(2x+3)

5 3/5 ÷ 2 1/3 then simplify answer and write it as a mixed number.

tatuchka [14]

5 3/5 ÷2 1/3 = 28/5 ÷ 7/3

then rearrange therefore =28/5×3/7

= 84/35

answer = 12/5
