Answer:
x = 37
Step-by-step explanation:
The angle on the left (x+15) and the angle on the right (4x-20) put together would have to equal 180 since a straight like is 180 degrees. If you add like terms the problem would be 5x-5=180. You would have to add 5 (since its negative in the problem) to 180, making the problem 5x=185. Now you divide by 5 (since it's multiplied by 'x') by both sides, which makes your answer x=37
<em>Add </em><em>n </em><em>to both sides of the equation. </em>
m= n +5
Answer:
x=6 y=7
(6,7)
Step-by-step explanation:
y=x+1 5x+3y=51
to solve this you can use the substitution method or anotherone i forgot the name of. so in with that being said, the substitution method is the wa to go.
start with the first equasion
5x+3y=51
substitute
5x+3(x+1)=51
distribute
5x+3x+3=51
add like terms
8x+3=51
solve equasion
8x=48
x=6
now onto the next equasion
y=x+1
substitute
y=6+1
add like terms
y=7
