Answer:
He bought 20 shirts
Step-by-step explanation:
shirts -- x
pants -- 3/4 of x
Therefore,
He bought --- 28(3/4 of x) pants and 40(x) shirts.
So, 28(3/4 of x) + 40(x) = 1220
=> 21x + 40x = 1220
=> 61x = 1220
=> x = 20
He bought 20 shirts and 15 pants.
Thenks and meak me brainliest :))
What equation??
xm =x+z
subtract x from each side
xm -x = z
factor out an x
x(m-1) = z
divide both sides by m-1
x = z/(m-1)
