Cross multiplying:-
18*x = 12*30
x = 360 / 18
x = 20 answer
Answer:
x=3 y=1
Step-by-step explanation:
-x-y=1
y=-x+4
x=-y-1
x=-y+4
x=-1+4
<u>x=3</u>
y=-3+4
<u>y=1</u>
Answer: x=15
Step-by-step explanation:
Since these are supplementary angles, we know that if we add them together we would get 180 deg. so....
(7x-10)+ (6x-5)=180
Kay so now we can combine like terms.
13x-15=180
Now we can add 15 to both sides.
13x=195
Finally Divide 13 on both sides.
X would then now equal 15.
