Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4
You take away from them so your answer will be 4,950
hope this help you with your question~~~~

if the washer and dryer cost $790 then you would divide 790 by 2.
then you will get $395
then you add 40 to $395 and will get $435
so the answer is $435
#2, Y=8, x=3
because if you subsitute those variables in,
8=3+5
4x3+8=20
Answer:
A
Step-by-step explanation:
An equivalent expression is an expression which is equal to (x-9)(2x^2-6x+3). You can expand or simplify an expression to make an equivalent expression. Apply the distributive property to form a new equivalent expression by multiplying (x-9) separately into the factor in parenthesis.
(x-9)(2x^2-6x+3) = x(2x^2-6x+3) - 9(2x^2-6x+3)
