Answer:

x=7

Step-by-step explanation:

3/4(x+21)=10 1/2

3/4x+63/4 = 21/2

3/4x= 21/2-63/4

3/4x= -21/4

x= (-21/4)/(3/4)

x= (-21/4)x(4/3)

x= -84/12

x=-7

What is algebra?

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given that:

The equation are

3/4(x+21)=10 1/2

3/4x+63/4 = 21/2

3/4x= 21/2-63/4

3/4x= -21/4

By cross multiplication

x= (-21/4)/(3/4)

Reverse the numerator and denominator

x= (-21/4)x(4/3)

x= -84/12

x=-7
