Answer:
x=5, x=-1
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other
y = -x + 7 and y = 0.5(x - 3)2
-x + 7 = 0.5(x - 3)^2
Distribute the right hand side by Foiling
-x+7 =.5 ( x^2 -3x-3x+9)
Combine like terms
-x+7 = .5( x^2 -6x+9)
Distribute the .5
-x+7 = .5x^2 -3x+4.5
Add x to each side
-x+x+7 = .5x^2 -3x+x+4.5
7 = .5x^2 -2x+4.5
Subtract 7 from each side
7 -7= .5x^2 -2x+4.5-7
0 = .5x^2 -2x-2.5
Multiply by 2 to clear the decimals
0 = x^2 -4x -5
Factor
0 = (x-5) (x+1)
Using the zero product property
x-5=0 x+1 =0
x=5, x=-1
<h2>Convert decimals to fractions</h2>
<em>To write 7.18 as a fraction, you must write 7.18 as the numerator and put 1 as the denominator. </em><em>Now multiply the numerator and denominator</em><em> by 10 until you get a whole number in the </em><em>numerator.</em>
<h3>
7.18 = 7.18/1 = 71.8/10 = 718/100</h3>
<em>And finally we have:</em>
<h3>7.18 a fraction is equal to 718/100</h3>

To solve this question, you want to try to get the variable alone on one side.
So, your starting equation is 7a-3=3+6a. You want to subtract 6a from both sides of the equation, so that the variable a is only on the left side of the equation.
So, after subtracting, your equation looks like a-3=3. Next, you want to add 3 to both sides, to cancel out the -3 on the left side of the equation.
If performed correctly, your equation should be a=6.
Your final answer is a=6.
