y=2x−15

4x+3y=−5


_________



4x+3(2x-15)= -5


4x+6x-45= -5


10x=-5+45


10x= 35


X=35/10


X= 3.5 or 3 and 1/2


Now solve for y

4x+3y=−5


4(3.5)+3y= -5


12.5+3y= -5


.40+3y= -5


3y= -5-0.40


3Y= -5.40


Y= -1.80


Answer (3.5, -1.80)

Solve 5c − c + 10 = 34. <br> −6 <br> 6 <br> 11 <br> −11
natima [27]

Subtract 10 and collect terms to get the variable term by itself on the left.

... 4c = 24

Divide by the coefficient of the variable, 4.

... c = 6

The appropriate choice is the second one:

... 6

_____

You don't actually have to sove the equation to find the right answer. You just need to see which answer works.

-6: 5(-6) -(-6) +10 = -14 ≠ 34

6: 5(6) -(6) +10 = 34 . . . . . . . this answer works (you can stop here)

11: 5(11) -(11) +10 = 54 ≠ 34

-11: 5(-11) -(-11) +10 = -34 ≠ 34
