Answer:

1.) a = r / x - b

2.) x = - 14

Step-by-step explanation:

1.) r = x ( a + b )

r / x = x / x ( a + b) ...( Divide each side by x )

r / x = a + b

r / x - b = a + b - b ... ( Subtracting each side by b) r / x - b = a

2.) x / 2 = -7

x / 2 × 2 = -7 × 2 .. ( multiplying each side by 2 )

x = - 14

Answer:

a = (r/x) -b

x = -14

Step-by-step explanation:

r=x(a+b)

Divide each side by x

r/x = a+b

Subtract b

r/x  -b = a

x/2=-7

Multiply each side by 2

x/2*2 = -7*2

x = -14

<h3>What is basic algebra ?</h3>

Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done.
