Answer:

See below

Step-by-step explanation:

[tex]4-3a=5-2a\\ 4=5+a\\ -1=a[/tex]

[tex]2(x+4)=3(5-2x)\\ 2x+8=15-6x\\ 8x+8=15\\ 8x=7\\ x=\frac{7}{8} [/tex]

[tex]0=3(x-2)-8\\ 8=3(x-2)\\ 8=3x-6\\ 14=3x\\ \frac{14}{3}=x [/tex]

[tex]4=-3p-5\\ 9=-3p\\ -3=p[/tex]

[tex]y-\frac{2y}{5}=3\\ 5y-2y=15\\ 3y=15\\ y=5[/tex]

[tex]\frac{3x-2}{4}=7\\ 3x-2=28\\ 3x=30\\ x=10[/tex]

[tex]x(6x-7)=0\\ x=0,x=\frac{7}{6} [/tex]

Can't do last one as variables are different
