two angles are supplementary if their sum is180.the larger angle measure four degrees more then seven times the measure of a small angle.if x represents the measure of the smaller angle and these two angle are supplementary angle find the measure of each angle.

help me please
We are given the smaller angle as x . Let the larger angle be y
As x and y are supplementary
the larger angle measure four degrees more then seven times the measure of a small angle.so
\[y=7x+4....................(2)\]From first equation we get
Let's substitute this in second equation
@ariana-help can you find x now?

@ariana-help tell me which part you don't get?
wat do i got to muli the numbers with
Did you understand how I got the last equation?
wat the answer
Let x be the smaller angle and 180 - x the larger of the two supplementary angles.
180 - x = 7x + 4
180 - 4 = 7x + x
176 = 8x
22 = x ------> smaller measure
180 - x = 158 ----> larger measure
22degrees & 158 degrees are the right answer.
no it was not
130 and 50
Post your work and answers, please. I would like to compare it to mine to pinpoint my error. Thanks.
the larger angle measure four degrees more then seven times the measure of a small angle. --> from the problem as posted
Your answers -->130 and 50
Checking your work:
the larger angle measure four degrees more then seven times the measure of a small
130 = 4+ 7(50)
130 = 4 + 350
130 = 354
Your answer is NOT correct.
