Question

3 x minus 2 upon 10 - X + 3 upon 7 + 4 x minus 7 upon 3 is equals to x minus one

Answer 1

3×(-2)/10-x+3/7+4x-7/3=x-1
-6/10-x+3/7+4x-7/3=x-1
-6/10+3/7+4x-7/3=x-1+x
-6/10+3/7-7/3+4x=2x-1
-6/10+3/7+7/3=2x-1-4x
-6/10+3/7+7/3=-2x-1
-6/10+[(3×3)+(7×7)]/21= -2x-1
-6/10+(9+49)/21= -2x-1
-6/10+58/21=-2x-1
[(-6×21)+(58×10)]/210= -2x -1
(-126+580)/210= -2x -1
454/210=-2x-1
454/210+1=-2x
(454+210)/210=-2x
664/210= -2x
(664/210)

Answer 2

Answer: x=4

Step-by-step explanation:

( 3x - 2 ) /10 - ( x + 3 )/7 + ( 4x - 7 )/3 = x- 1

[ 21(3x-2)-30(x +3)+70(4x-7)]/210 = x -1

63x -42-30x-90+280x-490=210(x-1)

313x - 622 =210x - 210

313x - 210x = 622 - 210

103x = 412

x = 412/103

x = 4
