The value of x is 35

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

Algebraic expressions are expressions consisting of variables, terms, constants and factors.

They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.

We have that;

5(x+20)= 7x+30

expand the bracket

5x + 100 = 7x + 30

collect like terms

5x -7x = 30 - 100

add like terms

- 2x = -70

Make 'x' the subject

x = -70/ -2

x = 35

Thus, the value of x is 35
