Step-by-step explanation:
<u>Step 1: Define</u>
10.5x - 1.9 = 19.1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1.9 to both sides: 10.5x = 21
- Divide 10.5 on both sides: x = 2
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 10.5(2) - 1.9 = 19.1
- Multiply: 21 - 1.9 = 19.1
- Subtract: 19.1 = 19.1
Here we see that 19.1 does indeed equal 19.1.
∴ x = 2 is a solution to the equation.
The player has a total of 18 goals scored and 6 assists made.
<h3>
Equation</h3>
Equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of goals scored and y represent the number of assists. Since the combined goals and assist is 24, hence:
x + y = 24 (1)
Also:
2x + y = 42 (2)
From equation 1 and 2:
x = 18, y = 6
The player has a total of 18 goals scored and 6 assists made.
