Question

What is this 8=a+3+4

Answer 1

$\bf Step-by-step~explanation:$

If we were to solve for a, we will need to isolate the variable.

$\bf Step~1:$

Add the like terms on the right side of the equation together.

$\bf 8=a+3+4\\8=a+7$

$\bf Step~2:$

Subtract 7 from both sides to move 7 to the other side.

$\bf 8(-7)=a+7(-7)\\1=a$

$\bf Step~3:$

Rewrite the equation so that the variable is at the beginning. This is the format most teachers prefer.

$\bf 1=a\\a=1$

$\large\boxed{\bf Our~final~answer:~a=1}$
