Question

Answer two questions about Equations A and B:

A. 5x = 20
B. x=4
1) How can we get Equation B from Equation A
Choose 1 answer:
A: Multiply/divide both sides by the same non-zero constant
B: Multiply/divide both sides by the same variable expression
C: Add/subtract the same quantity to/from both sides
D: Add/subtract a quantity to/from only one side
2: Based on the previous answer, are the equations equivalent? In other words, do they have the same solution?
A: Yes
B: No
PLS HELP

Answer 1

1) Choice A. We can divide both sides by 5 to solve for x.
2) Choice A, yes.
Let’s divide both sides of the equation by 5.

5x=20

5x/5 = 20/5

x = 4

The equations have the same solution, so they are equivalent
