Question

Drag each equation to show if it could be a correct first step to solving the equation

Answer 1

Answer:

3 + 4x = 36----->No

(4.3)+(4 . x)= 36------>Yes

4(3 + x)= 144--------->No

3+ x = 9-------> Yes

12 + x = 36------>No

12 + 4x = 36------->Yes

Step-by-step explanation:

The given equation is

$4(3 + x) = 36$

A correct first step is to expand the LHS to get:

$12 + 4x = 36$

Or to divide through by 4 to get:

$3 + x = 9$

Or just distribute to get:

$4 \cdot 3 + 4 \cdot \: x = 36$
