What is the solution for x in the equation? -4 + 5x − 7 = 10 + 3x − 2x

a. 4/21
b. 21/4
c. 4/13
d. 13/4

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
