Solve 45divx=10+15+20

$$45 \div x = 10 + 15 + 20$$

Solve for x

$$x=1$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$45=x\times 10+x\times 15+x\times 20$$

Combine x\times 10 and x\times 15 to get 25x.

$$45=25x+x\times 20$$

Combine 25x and x\times 20 to get 45x.

$$45=45x$$

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

$$45x=45$$

Divide both sides by 45.

$$x=\frac{45}{45}$$

Divide 45 by 45 to get 1.

$$x=1$$
