How are addition and multiplication used to solve a linear equation? - Answers

The multiplication is used to solve a liniar equation is when you have for example x/5=10 when you have a number divided by another number you need to multiply both sides with the denominator of x to get the number. In this case the answer is 50. Lets check 50/5=10 10=10 yes its right Addition is used to answer a linear equation when you have for example this equation: x-5=20 To get the answer you need to add the opposite o the number adding/subtracing x. In this example it is -5. So when you add the opposite you need to add 5 this will end up with x=25 lets check 25-5=20. yes its correct now lets use all the learning so far. to start lets start with an equation. x/2-5=10 first we will need to add 5 x/2=15 second we need to divide/multiply x=30 third you need to check 30/2-5=10 15-5=10 10=10 yes its correct
