Answer:
6 i think..
Step-by-step explanation:
We rewrite equations to make them simple or to solve them. Solving algebraic equations often means isolating the variable or rewriting the equation so that one expression is only the variable with a coefficient of 1
Option 1: 6a = 420 requires division property of equality to be solved
Step-by-step explanation:
Solving an equation means to find the value of a variable by isolating the variable on one side of the equation.
We will see all the options one by one.
<u>Option 1:</u>
In this option, 6 is multiplied with the variable so we have to divide the whole equation by 6 to find the value of a.
So we will use "Division property of Equality"
Dividing both sides by 6
Hence,
Option 1: 6a = 420 requires division property of equality to be solved
