Can someone please HELP me on how to do this

Answer:4)x= g-c5)x =u+k6)x = g-c7)[tex]a=\frac{k}{u}[/tex]8)[tex]x= \frac{g}{c}[/tex]9)[tex]a=\frac{4}{12m}[/tex]10)[tex]x= \frac{2c+3}{3}[/tex]11)[tex]a=\frac{n+p}{m}[/tex]12)[tex]a= \frac{ub}{k}[/tex]13)a= d -r + c14)[tex]x=\frac{np}{m}[/tex]Step-by-step explanation:4) g= c+xx= g-c5) u=x-kx =u+k6)g = c+x x = g-c7) [tex]u=\frac{k}{a} \\\\a=\frac{k}{u}[/tex]8) g=xc[tex]x= \frac{g}{c}[/tex]9) 12am = 4[tex]a=\frac{4}{12m}[/tex]10)-3x+2c = -32c = -3 +3x2c +3 = 3x[tex]x= \frac{2c+3}{3}[/tex]11) am= n+p[tex]a=\frac{n+p}{m}[/tex]12)[tex]u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}[/tex]13)a-c = d-ra= d -r + c14)xm= np[tex]x=\frac{np}{m}[/tex]
