Question

12x-3x=324 11y+7y-2y=400

Answer 1

12x-3x=324
9x=324
x=324/9
x=36

11y+7y-2y=400
16y=400
у=25

Answer 2

12х-3х=324
9х=324
х=324:9
х=36
Ответ 36

11у+7у-2у=400
16у=400
у=400:16
у=25
Ответ 25

Answer 3

12x - 3x = 324 Combine like terms: 9x = 324 Divide both sides by 9: x = 36

11y + 7y - 2y = 400 Combine like terms: 16y = 400 Divide both sides by 16: y = 25

So the solution to the equation is x = 36 and y = 25.
