the second one:
make the subject (p)
p+3=qp+r/(2)
..is wrong,, must be:
ans: p=r-6/(2-2q)
the third one:
make the subject (r)
p(r-q)=2+3(q-r)
..is lacking parenthesis,, must be:
ans: r=(2+3q+pq)/(p+3)
the last one is wrong,,
y=r-qp/(x) *transpose r to left side
y-r = -qp/x *multiply both sides by x
x(y-r) = -qp *divide both sides by (y-r)
x = (-qp)/(y-r)
so there,, =)
just like to check if ive got these right. if not can you help??
make the subject (q)
p(q+r)=2(q-p)
ans q=pr+2p/(2-p)
make the subject (p)
p+3=qp+r/(2)
ans p=r-6/(2-q)
make the subject (r)
p(r-q)=2+3(q-r)
ans r=2+3q+pq/(p+3)
make the subject (x)
y=r-qp/(x)
ans x=r-qp/(y)
