(pls im so slow someone help) Solve the system of linear equations by elimination.

x - 2y = -3

2x + 2y = 12

(x, y) = (3, 3)

Step-by-step explanation:

To apply the method of elimination, you must add the 2 equation if one of the variables is cancelled out. Luckily, the equations are already in a form where we can add them and y will be cancelled out.

Then we replace x on any equation to find y

so the solution is

x = 3 and y = 3

168

step-by-step explanation:

i am pretty sure that the answer is 168

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
