solve, using addition 5.4= x-1.3 write an integer or a decimal
5.4= x-1.3
5.4 + 1.3 = x - 1.3 + 1.3
? = x
5.4 = x-1.3
add 1.3 to both sides.
5.4+1.3 = x-1.3+1.3
5.4+1.3 = x
6.7 = x
check:
5.4 = x-1.3
5.4=6.7-1.3
5.4 = 5.4

To solve the equation 5.4 = x - 1.3 using addition, we need to isolate the variable x on one side of the equation.
Step 1: Add 1.3 to both sides of the equation:
5.4 + 1.3 = x - 1.3 + 1.3
6.7 = x
Therefore, the solution to the equation is x = 6.7.
