Answer:
![\displaystyle [-7, -7]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B-7%2C%20-7%5D)
Step-by-step explanation:
{2x - 6y = 28
{−x - y = 14
−⅙[2x - 6y = 28]
{−⅓x + y = −4⅔
{−x - y = 14

Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
<u>-b -2g= -$135------equation 2</u>
<u>2b -g = 0 --------- equation3</u>
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270
Hey there! I'm happy to help!
If something is 11 less, we are subtracting 11.
-11
We have 11 less than seven times a number x.
7x-11
The word is means equals.
7x-11=-4
Now we need to isolate the x. We add 11 to both sides.
7x=7
We divide both sides by 7.
x=1.
Have a wonderful day! :D
-6z+ 12
= -6(z -2) (distributive property)
The final answer is -6(z -2)~
