Question

PLEASE ANSWER HURRY WHICH ONE IS IT?

Answer 1

B

Explanation:

You can multiply both sides by c to remove the fraction part.

d(c) = ax + by/c(c)

dc = ax + by

Then subtract "by" from both sides to isolate x.

dc - by = ax - by + by

dc - by = ax

Then divide both sides by a to completely isolate the variable x.

(dc - by)/a = ax/a

(dc - by)/a = x

B

Answer 2

x = cd-by/ a

Explanation:

ax + by / c = d

ax + by = cd

ax = cd-by

x = cd-by/a
