James used substitution to solve this system of equations.
Which equation could be the result of his first step?
2x + 3y = 12
y = x + 1.5
y = 2x + 3y
2x + 3x + 1.5 = 12
2x + 3(x + 1.5) = 12
y = 2x + 3y + 1.5

idk the answer but just put a

step-by-step explanation:

nada

step-by-step explanation:

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
