Solve for x . Say the steps out
8 = x - 3
1.Goal is to get x by itself
2. use inverse operations
3. So you add 3 on both sides
4. bring down the x and you add 8+3
5. get x=11

Solve for x. Say the steps out
12x = 3
1. goal is to get x by itself (what is bothering the x)
2. use inverse operation the opposite of multiplication is division
3. So you divide the 12 on both sides
4. Cancel/cross out the 12
5. now you bring down the x and have
x=3/12
6. Always simplify the fractions So answer is
1/4
