$4 a + 2 b = 20$ $15 a + 5 b = 60$

Step 1

Reduce the system.

$b = 10 - 2 a, b = 12 - 3 a$

Step 2

Simplify the right side.

Step 2.1

Reorder $10$ and $- 2 a$ .

$b = - 2 a + 10$

$b = 12 - 3 a$

$b = - 2 a + 10$

$b = 12 - 3 a$

Step 3

Simplify the right side.

Step 3.1

Reorder $12$ and $- 3 a$ .

$b = - 3 a + 12$

$b = - 2 a + 10$

$b = - 3 a + 12$

$b = - 2 a + 10$
