Solve the system by substitution. y=−3x-2 -7x+3y=10 PLEASE HELP

enyata [817]

Y=-3x-2
subsitute -3x-2 for y
-7x+3(-3x-2)=10
distribute
a(b+c)=ab+ac
3(-3x-2)=-9x-6

-7x-9x-6=10
add like terms
-16x-6=10
add 6
-16x=16
multiply -1
16x=-16
divide 16
x=-1

subsitute
y=-3x-2
y=-3(-1)-2
y=3-2
y=1

x=-1
y=1

(x,y)

meriva

Answer:

4.5 foot is needed for a unit dozen bird house

Explanation:

Given Tina saw ¾ foot of wooden trim is being used for first 1/6 dozen bird houses

Therefore, we can write as,4

1/6 dozen = ¾ foot

For 1 dozen bird houses, we have to use the unitary method

1/6 dozen = ¾ foot

Therefore, 1 dozen or unit dozen = $\frac{\frac{3}{4}}{\frac{1}{6}}$

1 dozen = ¾ * 6 = $\frac{9}{2}$ foot = 4.5 foot

Therefore, 4.5 foot is needed for a unit dozen bird house
