\[3x = 216\]We need to find \(3x + 4x = 7x\)

how would we do that?

no u do 3/4 is equal to 216/x

i still dont get it

Can you find \(x\)?

Do it either way.

cross multiply the 3 times x and 4 times 216

but i cant find the value for x

then after that u divide each side by 3and then u get ur answer

im still confused cause i cant find the value for x but 4*216=864

now take 864 divided by 3 and whats that equal

288

is that one of ur choices

they dont give me choices they just want me to type my answer

oh then ur answer is 288

was i right
