Question

What is the correct solution to the equation 2x+7 = 19 a) x = 6 b) x = 13 c) x = 12 d) x = 2.5

Answer 1

Answer:

a

Step-by-step explanation:

2x +7= 19

2x= 19 -7 (-7 on both sides)

2x= 12 (simplify)

x= 12 ÷2

x= 6

Answer 2

Answer:

a

Step-by-step explanation:

Given

2x + 7 = 19 ( subtract 7 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6
