Answer:
Linear: 3x +9 =2x
Non Linear: x+2y=1 and x = y
X = 5
since we know y= 5 + x , plug this into y in the second equation.
2x + 2 (5 + x) = 30
distribute 2 into the 5 and x
2x + 10 + 2x = 30
combine like terms
4x + 10 = 30
subtract 10 from both sides
4x = 20
divide four by both sides to isolate the variable
x = 5
• y is vertically opposite to the one whose measure is 43º.
So,
y = 43º.
• x and y are supplementary angles:
x + y = 180º
x = 180º <span>– y
x = 180º </span><span>– 43º
x = 137</span><span>º.
</span><span>• z and x are vertically opposites.
So,
z = x
z = 137º<span> <</span></span>——<span><span>— this is the answer.</span>
I hope this helps. =)
