Question

Please help! This is algebra work and it’s due tmr TT

(Please explain how you did the problem)
subject: solve the system of linear equations by graphing

x + y = 5
y - 2x = -4

Graph:

Answer 1

The solution is (3,2).

Explanation:

When you are solving simultaneous equation using graphs, you have to look at their intersection point.

In this graph, both equations intersect at (3,2) so the solution will be (3,2).

Test,

x + y = 5

3 + 2 = 5

y - 2x = -4

2 - 2(3) = 4

2 - 6 = 4
