<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions made up;

  • Factors
  • variables
  • terms
  • constants

They also consist of mathematical operations such as addition, multiplication, division, subtraction, parenthesis, brackets, etc

We have the expression as;

7.5x = 5.5x + 10

collect like terms

7.5x - 5.5x = 10

subtract the like terms

2.0x = 10

Make 'x' the subject

x = 10/2. 0

x = 5

Thus, the value of x is 5

Rainbow [258]

Answer:

96°

Step-by-step explanation:

An angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.

x = 168/2 = 84°

A straight angle is 180 degrees

y = 180 - x = 180 - 84 = 96°
