Answer:
14
Step-by-step explanation:
Because right angles are 90 degrees, we need to subtract 34 from 90 which gets us 56. That means 56 = 4x, so 56/4 = 14, therefore X = 14.
Hope this helps!
Answer:


Step-by-step explanation:
Given :
........................... equation 1
........................... equation 2
solving by substitution method , substitute
into equation 1 , that is




substitute
into equation 2 to find the value of y , that is


Answer:
x = +3 , y = +3
Step-by-step explanation:
Just solve for x in eq1
to become: x=6-y
then substitute it in eq2
6-y-y=0
6-2y=0
2y=6
y=+3
And finally substitute the value of y in any eqs to find the value of x.
I hope that it's a clear explanation.
