Q. What value of w is a solution to this equation?w−4=2Choices:(A)w=4(B)w=6
Add 4 to both sides: To solve for w, we need to isolate w on one side of the equation. We can do this by adding 4 to both sides of the equation to cancel out the −4 on the left side.w−4+4=2+4
Simplify the equation: Now, we simplify both sides of the equation. w=2+4
Find the value of w: Adding 2 and 4 gives us the value of w.w=6
Check answer choices: We check the answer choices to see if our solution matches one of them.Choice (A) w=4 does not match our solution.Choice (B) w=6 matches our solution.
