Question

Drow the graph of the equation 2x+y=7. From the graph :a find whether the point (3,4) line on the graph. B find whether x=3,y=1 is a solution of the equation. C find the valu of x, when y=1. D find the point where the eqution meets the x-axis.

Answer 1

Answer:

3,3

Step-by-step explanation:

B:2x+y=7

if x=3,y=1

2(3)+(1)=7

6+1=7

C:2x+y=7

if y=1

2x+(1)=7

2x+1=7

2x=7-1

2x=6

x=6÷2

x=3
