Question

Решить уравнения.
1. 29+14(9-х)=19-2х
2. 96(х-1)-(7х-64)=38(2-х)+3(17+2х)+83

Answer 1

1.29+126-14x=19-2x
155-14x=19-2x
-14x+2x=19-155
-12x=-136
x=11,4
2.96x-96-7x+64=76-38x+51+6x+83
89x-32=210-32x
89x+32x=210+32
121x=242
x=242/121=2

Answer 2

1.
29+14(9-х)=19-2х
29+126-14x=19-2x
-14x+2x=19-29-126
-12x=-136
x=-136:(-12)
x=$11 frac{1}{3}$

2.
96(х-1)-(7х-64)=38(2-х)+3(17+2х)+83
96x-96-7x+64=76-38x+51+6x+83
96x-7x+38x-6x=76+51+83+96-64
121x=242
x=242:121
x=2
