Answer:

X = 22

Step-by-step explanation:

Given

Represent Emma with E and Nikki with N

From the question, we have that:

E = 1 + 2N

and

E = 15

Required

Determine the X number of goals

Substitute 15 for E in E = 1 + 2N

15 = 1 + 2N

Subtract 1 from both sides

15 -1 = 1 - 1 + 2N

14 = 2N

Divide both sides by 2

\frac{14}{2} = \frac{2N}{2}

\frac{14}{2} = N

7 = N

N=7

This implies that Nikki scored 7 goals in total

The X number of goals is then calculated as:

X = N + E

X = 7 + 15

X = 22

faust18 [17]
<span>Subtracting 2x from both sides of the equation would be a reasonable first step in solving this equation as it properly combines like terms to the left side of the equation. It quickly shows that the next step would be adding 1 to both sides of the equation, which would have us arrive at the answer of x = 5.</span>
