Exercise 35 Page 506

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

x=2.46

Practice makes perfect

The variable term is already on the left-hand side of the equation, so we will start by multiplying both sides by 2.1, so we can find the value of x.

x/2.1=4.1/3.5

LHS * 2.1=RHS* 2.1

x=2.1* 4.1/3.5

MoveLeftFacToNum

a*b/c= a* b/c

x=8.61/3.5

a/b=a÷ b

x=8.61÷ 3.5

Use a calculator

x=2.46

The solution to the equation is x=2.46.
