Solve for y: 2x-3y=12 When X=4

y= -4/3

Step-by-step explanation:

To solve for y when x=4, substitute 4 in for x

2x-3y=12

2(4)-3y=12

Multiply

8-3y=12

Subtract 8 from both sides

-3y=4

Divide by -3 on both sides

y= -4/3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
