Please help me with this homework using the substitution method

(5, -2)

Step-by-step explanation:

Let's solve the first equation for x:  If x + y = 3, and if we subtract y from both sides, we get x = 3 - y.  Next, substitute 3 - y for x in the second equation:

3(3 - y) + 2y = 11, or

9 - 3y + 2y = 11

Combining like terms:  -3y + 2y = 11 - 9, or

-y = 2, or y = -2.

Then, from the equation x = 3 - y, which we found earlier,

x = 3 - (-2) = 5

Then the solution is (5, -2)

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
