First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
6 and 8 I believe is the answer
I believe she is ten because if last year Ellen was twice Maja's age that would be 11 minus one because it was last year. So 10 years older now so whats ten doubled because she was twice her age so 10+10=20. So now we know Maja is 10 and Ellen is 21.
