Question

5x + 2y = 7
y = x + 1

What is the solution set of the given system?

{(5/7, 12/7)}
{(12/7, 5/7)}
{(9/7, 16/7)}
{(16/7, 9/7)}

Answer 1

use substitution method

Answer 2

U hv to put the value of y frm second equation into first equation

Answer 3

Ok its better you start of with substitution

Answer 4

So solve 5x+2(x+1)=7

Answer 5

5x+2(x+1)=7
x=?

Answer 6

Remember Pemdas and distribute first

Answer 7

From there combine like terms and then solve for x

Answer 8

i don't know what are you guys talking about

Answer 9

5x+2x+2=7
Right

Answer 10

7x=5

Answer 11

@john_97

Answer 12

divide 7 by both sides for 7x=5
then you got the x value

Answer 13

5x+2y=7
y=1+x Substitute the value for y in the first equation

5x+2(1+x)=7 Now Distribute and Combine like terms
5x+2x+2=7
-2 -2
7x=5
/7 /7

x=5/7

Now substitute the value of x in the any equation to find y
