Question

HELP! Can someone please explain to me how to solve this question?

"At what point do the equations intersect? y = 25x + 54 and y = 15x + 14

Answer 1

7,68

Explanation:

y=2x+54

y=15x+14

you can do elimination so you need to multiply the x's by -15 and 2

y=-30x+54

y=30x+15

the x's are canceled out and you add the remaining

y=54. y=68

y=15

To find x you makes an equation of one of the equations given

68=2x+54

14=2x

7=x

Answer 2

`(-3.1, -32.5)`

Explanation:

Set the equations equal to each other: 25x+45=15x+14

Solve for x: 10x = -31

Solve for x: x=-3.1

Plug the x value back into one of the equations to find the value of y:

y = 15 (-3.1) +14

y = -32.5
