Question

Determine the solution by using substitution. Write your answer as a point below (x,y).

Answer 1

Answer:

(2,-2)

Step-by-step explanation:

4x-10=-3x+4

+10           +10

4x=-3x+14

+3x . +3x

7x=14

/7  /7

x=2

y=4(2)-10

y=8-10

y=-2  

sorry i took so long i was cooking pasta

Answer 2

Answer:

(2,-2)

Step-by-step explanation:

To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
