Question

Consider the sequence of steps to solve the equation: 5(x - 3) = 7x 2 step 5

Answer 1

Answer:Solving 5(x - 3) = 7x/2

Step 1 ⇒ 10(x - 3) = 7x

Step 2 ⇒ 10x - 30 = 7x

Step 3 ⇒ 3x - 30 = 0 . . . . . . addition (or subtraction) property of equality

Step 4 ⇒ 3x = 30

Step 5 ⇒ x = 10

Answer 2

5(x-3) = 14 (you have to simplify 7 x 2 = 14)

x-3 = 14/5 (divide both sides by 5)

x= 14/5 + 3 (add 3 to both sides)

x= 29/5 (simplify)
