Answer:
-600
Step-by-step explanation:
Jackson's initial score was 300, then his later score became -300, so you know that he had to lose points.
-300=300+x
** x represents the point change
Then just solve the equation by getting x by itself. You do this by subtracting 300 from both sides:
-300=300+x
-300 -300 = -300-300+x
-600 = x

Answer:
All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
7x− 3 = − 3 + 7x
Step 1: Simplify both sides of the equation.
7x − 3 = −3 + 7x
7x + −3 = −3 + 7x
7x − 3 = 7x − 3
Step 2: Subtract 7x from both sides.
7x− 3 −7x = 7x −3 −7x
−3 = −3
Step 3: Add 3 to both sides.
−3 + 3 = −3 + 3
0 = 0
