Question

3x+4y=16
-4x-3y=-19

Answer 1

should the 2nd equation be

-4x -3y = -19...?

Answer 2

and what do you need to do to the 2 equations...?

Answer 3

Yes

Answer 4

Express the answer in a ordered pair in a format (a,b)

Answer 5

ok... so you are solving simultaneously..? or graphically..?

Answer 6

Graphically

Answer 7

ok.... so find the intercepts for both lines

3x + 4y = 16

is x = 0... you can find the y- intercept...

so you are solving

4y = 16 the line cuts the y-axis at (0, answer)

similar for the x- intercept... let y = 0... so you are solving

3x = 16

the line cute the x axis at (answer, 0)

now draw a line through the 2 points....

same process for the 2nd line....

find the x and y intercepts....

draw the line...

read off where they intersect...

hope it helps
