Solve the system of equations below.

5.1 - 2y=18

3. x+3y=15

Answer: y = - 6.45 and y=5-x

Step-by-step explanation:

Subtract 5.1 from both sides.

-2y = 18-5.1

Simplify 18 - 5.1 to 12.9

-2y=12.9

Divide both sides by - 2

y = - 12.9/2

Simplify 12.9/2 to 6.45

y=-6.45

Factor out the common term 3.

3 (x+y) = 15

Divide both sides by 3.

x+y = 15/3

Simplify 15/3 to 5.

x+y = 5

Sub. x from both sides

y = 5-x
