Step-by-step explanation:
X = 11 / cos(32)
X= 12.97096
<h3><u>The value of the first number, x, is eual to 2.</u></h3><h3><u>The value of the second number, y, is equal to -1.</u></h3><h3><u>The value of the third number, z, is equal to 8.</u></h3>
x + y + z = 9
y = x - 3
z = 2x + 4
Because we have values for y and z, we can find the exact value of x, which we can use to find the exact values for the other variables.
x + x - 3 + 2x + 4 = 9
<em><u>Combine like terms.</u></em>
4x + 1 = 9
<em><u>Subtract 1 from both sides.</u></em>
4x = 8
<em><u>Divide both sides by 4.</u></em>
x = 2
Now that we have a value for x, we can plug this value in to each other x value to solve for y and z.
y = 2 - 3
y = -1
z = 2(2) + 4
z = 8
