Does the ordered pair, (1, 5/2) satisfies the given equation<br> 3x-3y=-3 ?

vampirchik [111]

Answer:

Ordered pair, (1, 5/2) does not satisfy the given equation 3x-3y=-3

Step-by-step explanation:

$3x-3y=-3$

Here $(x, y) = (1, \frac{5}{2} )$

$3(1)-3(\frac{5}{2} )=-3$

$3- (\frac{15}{2} )=-3\\6-15=-6\\-9\neq -6$

2(x+1)+3x=37 *what is x??

irina1246 [14]

2(x+1)+3x=37

simplifythe left side:

2x +2 +3x = 37

Combine like terms:

5x +2 = 37

Subtract 2 from both sides:

5x = 35

Divide both sides by 5:

x = 7
