Convert the equation into slope-intercept form 2x+3y=9
The correct answer is = because 4/6 simplifies to 2/3
L x (times) w ( length times width) 9x4=36 I think.
20p = 40ck
1/2 pizzas to cheesecakes.
The easiest way to solve this is by elimination.
3x - y = 6
6x + y = 21
Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:
9x = 27
Then solving for x leaves you with x = 3
Then you take the x value of three and plug it into to either of the equations, so
3(3) - y = 6
9 - y = 6
subtracting 9
-y = -3
then dividing by -1
y = 3
so the solution is x = 3 y = 3 or (3,3)
