<u>The system of equation</u>
First equation
x = 2y + 7
Second equation
3x - 2y = 3
<u>Substitute x with (2y + 7) in the second equation</u>
3x - 2y = 3
3(2y + 7) - 2y = 3
use distributive property
3(2y) + 3(7) - 2y = 3
6y + 21 - 2y = 3
add like terms
6y - 2y + 21 = 3
4y = 3 - 21
4y = -18
y = -18/4
y = -4.5
<u>Substitute y with its value, which is -4.5, in the first equation</u>
x = 2y + 7
x = 2(-4.5) + 7
x = -9 + 7
x = -2
<u>The solution is</u>
<u />(x,y) = (-2, -4.5)
Answer:
9x + 14
Step-by-step explanation:
You need to add like terms. Add your x's together and your constants together:
5x + 4x + 6 + 8
9x + 14
Answer:
2.6, 2.6081, 2.68, 3.119
Step-by-step explanation:
Look at the number before the decimal first. After look at the decimal points, the one with the smallest amount will be the least greatest (2.6) because it has no numbers after it.
