Ali and Khamis are solving 4a-5b=7 for b. Is either of them correct ? Explain. PLS I'LL MARK YOU BRAINLIST DIRECTLY !!!

Ali is correct

Step-by-step explanation:

khamis is wrong

he got his negative numbers and positive numbers mixed up when taking it to the other side

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
