Question

Solve for r: 3x+r/2=14

Answer 1

3x=28-r

Steps:
1. remove the division
a. Multiply the division by 2 to make a zero, which you can now remove.
b. Multiply the answer by 2 also, to make 28.
c. You now have this equation: 3x+r=28
2. remove the number stuck to x by multiplication
a. divide 3x by 3 to make x.
b. divide 28 by 3 to make 9 and one third.
b. You now have this equation: x+r=9
$\frac{1}{3}$
