Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
7+1.25x=43.25
-7. - 7.00
____________
1.25x = 36.25
___________
1.25x. 1.25
x = 29
OK so to solve this we will subtract 16x from 2x to get -14x
-14x - 4y + 3x^2 + 7y
add - 4y and 7y to get 3y
-14x + 3x^2 +3y
and then to simplify we are going to move the -14x
3x^2 +3y - 14x
