Question

A+b=25a + 2b=3​

Answer 1

Ответ:

a+b=2

a=2-b

5(2-b)+2b=3

10-5b+2b=3

-3b=-7

b=7/3=>2 целых 1/3

Объяснение:

Answer 2

To solve the system of equations:

A + B = 25 ...(Equation 1) a + 2B = 3 ...(Equation 2)

We can use the method of substitution to solve for the variables A and B. Here's the step-by-step process:

Step 1: Solve Equation 1 for A in terms of B: A = 25 - B

Step 2: Substitute the value of A in Equation 2: (25 - B) + 2B = 3

Simplifying the equation: 25 - B + 2B = 3 25 + B = 3 B = 3 - 25 B = -22

Step 3: Substitute the value of B back into Equation 1 to solve for A: A + (-22) = 25 A - 22 = 25 A = 25 + 22 A = 47

So the solution to the system of equations is A = 47 and B = -22.
