2x + ________ = 11 has the solution – 4

Solution:

Let’s 2x + A = 11 has the solution – 4.

Then, solve the equation.

2(– 4) + A = 11

– 8 + A = 11

A = 11 + 8

x = 19

Hence 2x + 19 = 11 has the solution – 4.

✦ Try This: 3x + ________ = 9 has the solution 2.

Let’s 3x + A = 9 has the solution 2.

Then,

3(2) + A = 9

6 + A = 9

A = 9 – 6

x = 3

Hence 3x + 3 = 9 has the solution 2.
