In Exercises 5-14, solve the equation. Justify each step.
Check your solution. (See Example 1.)
5. x+5=8
6. m + 9 = 2
7. y - 4 = 3
8. s-2=1
9. w+ 3 = - 4
10. n-6= - 7
11. - 14 = p - 11
12. 0 = 4 + 9
13. r +(-8) = 10
14. t-(-5) = 9

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

ok then what happened.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
