Andrei [34K]

Answer:

solution given:

principal [P]=$850

so

Total balance=S.I.+P=$544+$850=$1394.

Y=2x+5 and y=3x+2 using substitution strategy
WINSTONCH [101]

Answer:

Hi there the answer will be (3,11)

Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.

2x+5=3x+2

Then you subtract 2x on both sides to get the x's on the same side

and you get 5=x+2

Then you subtract 2 on both sides, and you get x to equal to 3

then you plug x into any equation to get y to equal 11

y= 2(3)+5
