We will be using PEMDAS rule here :

P - Parentheses first

E - Exponents (ie Powers and Square Roots, etc.)

MD - Multiplication and Division (left-to-right)

AS - Addition and Subtraction (left-to-right)

8+2(12-5)

Step 1:

Solving parenthesis first:

8+2(7)

Step 2:

Multiplying 2*7

8+14

Step 3:

Adding 8 and 14

Answer is 22

For what values of h and k does the linear system have infinitely many solutions? 2x1 + 5x2 = −1 hx1 + kx2 = 7

Kruka [31]

Answer:

The values of $h$ and $k$ for a linear system with infinitely many solutions are -2 and 5, respectively.

Step-by-step explanation:

Let $2\cdot x_{1}+5\cdot x_{2} = -1\cdot h\cdot x_{1} + k\cdot x_{2} = 7$ , if this linear system has infinitely many solutions, then the following conditions must be met:
