The steps to solve the equation x + 3 / 4 = X-1 / 8 are urgent, and they will be handed in tomorrow

The steps to solve the equation x + 3 / 4 = X-1 / 8 are urgent, and they will be handed in tomorrow

Multiply by (x + 4) (x-1)
3(x-1)=8(x+4)
3x-3=8x+32
5x=-35
x=-7
The fractional equation needs to be tested
By testing, x = - 7 is the solution of the equation

0.6 times (x-0.6) = 0.6, due tomorrow

6 times (x-0.6) = 0.6
x-0.6=0.6÷0.6
x-0.6=1
x=1+0.6
x=1.6

X divided by 5 = 1.4, solve the equation, quick, I'll hand it in tomorrow!

x÷5=1.4
x=1.4×5
x=7

[(x △ 2 + 9)] / [(x △ 2-9)] = 5 / 8 urgent to hand in tomorrow

[(x÷2+9)]÷[(x÷2-9)]=5/8
(x+18)÷(x-18)=5/8
8(x+18)=5(x-18)
8x+144=5x-90
8x-5x=-90-144
3x=-234
x=-78
