Question

Make x subject of the formula

1. a÷ x + b ÷x=1

2. a(x+b) = c

3. ax= b(c+x)

4. a(b -x) = cx

5. x÷2a + × ÷ 3a= b

6. x(a-b) = b ( c-x)

Answer 1

`{ \bf{1.}} \\ { \tt{ (a)/(x) + (b)/(x) = 1 }} \\{ \boxed { \tt{x = a + b}}} \\ \\ { \bf{2.}} \\{ \tt{ax + ab = c}} \\ { \boxed{ \tt{x = (c - ab)/(a) }}}`

`{ \bf{1.}} \\ { \tt{ (a)/(x) + (b)/(x) = 1 }} \\{ \boxed { \tt{x = a + b}}} \\ \\ { \bf{2.}} \\{ \tt{ax + ab = c}} \\ { \boxed{ \tt{x = (c - ab)/(a) }}} \\ \\ { \bf{3.}} \\ { \tt{ax - bx = bc )}} \\ { \boxed{ \tt{x = (bc)/(a - b) }}} \\ \\ { \bf{4.}} \\ { \tt{ab = cx + ax}} \\ { \boxed{ \tt{x = (ab)/(c + a) }}} \\ \\ { \bf{5.}} \\ { \tt{ (x)/(2a) + (x)/(3a) = b }} \\{ \tt{x(3a + 2a) = 6 {a}^(2)b }} \\ { \boxed{ \tt{x = \frac{6 {a}b }{5} }}} \\ \\ { \bf{6.}} \\ { \tt{ax - bx = bc - bx}} \\ { \boxed{ \tt{x = (bc)/(a) }}}`
