Question

90-x+3x-10=180
What would be the answer to this please and give step by step if it's not to much to ask for.

Answer 1

a. Add all like terms: 80+2x = 180
b. Move all constant terms to the answer’s side: 2x = 180
c. Divide both sides by same number: 2x/2= x= 180/2
d. Answer: x= 90

Answer 2

$90 - x + 3x - 10 = 180$

$(90 - 10) + ( - x + 3x) = 180$

$80 + 2x = 180$

$2x = 180 - 80 = 100$

$x = \frac{100}{2} = 50$

Answer: x = 50

Ok done. Thank to me :>
