10*(x-2)=2*(8-x) 15-(5x+3)=17-(8x+4)

Question

10*(x-2)=2*(8-x)
15-(5x+3)=17-(8x+4)

Answer 1

Первое уравнение
10*(x-2)=2*(8-x)
10x-20=16-2x
10x+2x=16+20
12x=36
x=36/12
x=3

Второе уравнение
15-(5x+3)=17-(8x+4)
15-5x-3=17-8x-4
-5x+8x=17-4+3-15
3x=1
x=1/3

Answer 2

10x-20=16-2x
10x+2x=16+20
12x=36
x=3
10×3-20=16-2×3
0=0
