Question

Solve the system of equations by graphing.

y = 1/2x + 3
y =4 x + 10

Answer 1

I hae graphing....but an algebraic approach to it...is see that y = two different things? well that must mean that those two things are equal as well...

so we can do this

1/2x + 3 = 4x + 10

now just get all the like terms on one side

1/2x - 4x = 10 - 3

1/2x - 8/2x = 7

-7/2x = 7

now multiply both sides by -2

7x = -14

divide by 7

x = -2

:)

Answer 2

y = 2

Answer 3

but how do u graph it

Answer 4

@Soumyadeep ..if it were 2..the top equation would = 4 and the bottom would = 18

Answer 5

and to graph it...it would look something like

Answer 6

Sorry boss! didnt check the other one!

Answer 7

Actually I had 2 at first too lol just had to recheck myself and say the mistake
