If lane's are span is 61 inches. his height is 1/4 foot long than his arm span. his height is <span>5 ft 3 inches </span>
The first step of solving this is to isolate the variable y in the first equation.
3x - y = -2 Subtract -3x from both sides
- y = - 3x - 2 Divide both sides by -1
y = 3x + 2
Now, substitute that y value into the second equation.
2x^{2} - y = 10 Substitute
<span>2x^{2} - (3x + 2) = 10 Multiply all of the numbers in the parentheses by -1
2x^{2} - 3x - 2 = 10
</span>
<span>So the correct answer choice is D) 2x^{2} -3x - 2 = 10.</span>
