Question

Choose the graph below that represents the solution to the system of equations

y=3x+2


10x+2y=20

Answer 1

Answer:

The solution is (1, 5)

Step-by-step explanation:

Here two equation of straight lines are given.

Two equations can intersect each other at a point.

The given equations are,

1. $y = 3x + 2$
2. $10x + 2y = 20\\ 5x + y = 10\\y = 10 - 5x$

Equating both 1 and 2 we get,

$10 - 5x = 3x + 2\\8x = 8\\x = 1$

Hence, from 1 we get, $y = 3+2 = 5$
