Urgent va roooggg!

Answer 1

5x+3 (x-6)=7x+13
3 (x-6) = 3x - 3×6 = 3x - 18
5x+3x-18=7x+13
8x-18=7x+13
8x-7x=13+18
x=31

5 (x-7)-2x=x-41
5 (x-7= 5x-35
5x-35-2x=x-41
3x-35=x-41
3x-x=41+35
2x=76
x=76:2
x= 38

4 (x+5)-3 (x-3)=2 (x+15)
4(x+5) = 4x + 20
3 (x-3) 3x-9
2 (x+15) = 2x +30
4x+20-3x-9 = 2x+30
x+11=2x+30
x-2x =30-11
-x = 19
x= -19

6x+4 (x-8)=9x+21
4 (x-8) = 4x-32
6x+4x-32=9x+21
10x-32= 9x+21
10x-9x=21+32
x= 53

7 (x-9)-4x=x-39
7 (x-9) = 7x-63
7x-63 -4x=x-39
3x-63=x-39
3x-x= 39+63
2x= 102
x= 102÷2
x= 51

5 (x+2) - 4 (x-2)=3 (x+8)
5x+10-4x-8= 3x - 24
x+2 = 3x-24
x-3x=-24-2
-2x = -22
-x= -22:2
-x= -11
