Solve 72/60=43+x/40

$$\frac{ 72 }{ 60 } = \frac{ 43+x }{ 40 }$$

Solve for x

$$x=5$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 120, the least common multiple of 60,40.

$$2\times 72=3\left(43+x\right)$$

Multiply 2 and 72 to get 144.

$$144=3\left(43+x\right)$$

Use the distributive property to multiply 3 by 43+x.

$$144=129+3x$$

Swap sides so that all variable terms are on the left hand side.

$$129+3x=144$$

Subtract 129 from both sides.

$$3x=144-129$$

Subtract 129 from 144 to get 15.

$$3x=15$$

Divide both sides by 3.

$$x=\frac{15}{3}$$

Divide 15 by 3 to get 5.

$$x=5$$
