Answer:
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w

Answer:
-1/9
Step-by-step explanation:
-7/9 + 2/3 also equals to 2/3 - 7/9
Now make the denominator same
LCM of 3 and 9 = 9
2/3 = 6/9
∴ 6/9 - 7/9 = -1/9
Step-by-step explanation:
Given
2x - 5 = 7
2x = 7 + 5
2x = 12
x = 12 / 2
x = 6
Hope it will help :)❤
