Question

Solve for x: (x+4) = 7.(1 point) 2 Ox=3 Ox=5 Ox=6 O x = 10

Answer 1

Answer:

A

Step-by-step explanation:

So we have the equation:

$x+4=7$

To solve for x, subtract 4 from both sides:

$(x+4)-4=(7)-4$

The left side cancels. Subtract on the right:

$x=3$

So, the value of x is 3.

And our answer is A.

And we're done!
