Answer:
x = 5
Step-by-step explanation:
14x + 22x = 180
36x = 180
x = 5
Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
Answer:
6x = 12
Step-by-step explanation:
2x + 3y - 10 = 0
4x - 3y - 2 = 0
add the two equations
2x + 3y - 10 = 0
4x - 3y - 2 = 0
--------------------
6x -12 = 0
add 12 to each side
6x -12 +12 = 0+12
6x =12
divide by 6
6x/6 =12/6
x =2
