Answer:

(1,4)

x= 1

y= 4

(I checked on desmos and this is correct)

Step-by-step explanation:

I'm going to solve this by substitution

To do this we need to get a variable by istelf in any equation

We'll start with 18x-2y=10

We can add 2y and divide by 2 to get

y=9x-5

This is what y will equal for now and we can plug this in for y in the second equation

3x+16(9x-5)=67

This is rather easy to solve

147x-80=67

147x=147

this means that x=1

We can then use this value for x and plug it into any equation

let's just do the first one

18*1-2y=10

This is easy to solve as well and you should get

-2y=-8

y=4

this means that x=1

y=4

WILL GIVE BRAINLIEST, RATING, AND THANKS!
Mashutka [201]

-10(-2)+y = 4

20 + y = 4

y = -16

----------------

-10(-1)+y = 4

10 + y = 4

y = -6

----------------

-10(0) + y = 4

0 + y = 4

y = -4

----------------

-10(1)+y = 4

-10 + y = 4

y = 14

----------------

-10(2)+y = 4

-20 + y = 4

y = 24

----------------

I hope thi helps

Help please! It would really be nice and I will reward a brainliest to the right and best answer!
Nikolay [14]
Well is the length is 4 ft, and 1 ft is 12 inches we need to do 12×4, which is 48.

So now we know that the length is 48, and the height is 4, so it would be 48×4, which gives us our answer, 192 inches!
