Simplifying 6y + 1 = 21y + 13

Reorder the terms: 1 + 6y = 21y + 13
<span>Reorder the terms: 1 + 6y = 13 + 21y

</span><span>Solving 1 + 6y = 13 + 21y

</span><span>Solving for variable 'y'.

</span><span>Move all terms containing y to the left, all other terms to the right.

</span><span>Add '-21y' to each side of the equation. 1 + 6y + -21y = 13 + 21y + -21y

</span><span>Combine like terms: 6y + -21y = -15y 1 + -15y = 13 + 21y + -21y

</span><span>Combine like terms: 21y + -21y = 0 1 + -15y = 13 + 0 1 + -15y = 13

</span><span>Add '-1' to each side of the equation. 1 + -1 + -15y = 13 + -1

</span>Combine like terms: 1 + -1 = 0 0 + -15y = 13 + -1 -15y = 13 + -1
Combine like terms: 13 + -1 = 12 -15y = 12
Divide each side by '-15'. y = -0.8
<span>Simplifying y = -0.8</span>

Name the property of equality that justifies the statement: if p=q, then q=p
Ostrovityanka [42]

Answer : - Symmetric property of equality tells that for all real numbers p and q, if p=q then q=p which means if we interchange the sides of an equation then the equation is still a true statement .

For example :-

1. We know that 4+5 =9 then by symmetric property we can also say that 9=4+5.

2. If 5x+5=7 then by symmetric property of inequality 7=5x+5.
