Question

Помогите пожалуста... я вам дам 15 баллов 1)(83х+77х-159х)-(87+95)=24 2)127+(95х-94х)=212 3)(83х-82х)+317=502

Answer 1

1)(83х+77х-159х)-(87+95)=24

83х+77х-159х-87-95-24=0

х-206=0

х=206

2)127+(95х-94х)=212

127+95x-94x-212=0

x-85=0

x=85

3)(83х-82х)+317=502

83х-82х+317-502=0

х-185=0

х=185

Answer 2

1) (83x + 77x - 159x) - (87 + 95) = 24 Simplify the left side of the equation: (83x + 77x - 159x) - (87 + 95) = 24 (240x - 282) = 24 Add 282 to both sides of the equation: 240x = 306 Divide both sides by 240: x = 306/240 x = 1.275

2) 127 + (95x - 94x) = 212 Simplify the equation: 127 + x = 212 Subtract 127 from both sides: x = 212 - 127 x = 85

3) (83x - 82x) + 317 = 502 Simplify the equation: x + 317 = 502 Subtract 317 from both sides: x = 502 - 317 x = 185

So the solutions to the equations are: 1) x = 1.275 2) x = 85 3) x = 185
