Indefinite amount of solutions.
Answer:
y = 2
Step-by-step explanation:
Addition Method:
4x - 2y = 6
2x + y = 7
-2(2x + y) = -2(7)
4x - 2y = 6
-4x - 2y = -14
-4y = -8
y = 2
Substitution Method:
4x - 2y = 6
2x + y = 7
-2y = 6 - 4x
2y = 4x - 6
y = 2x - 3
2x + (2x - 3) = 7
4x - 3 = 7
4x = 10
x = 2.5
2(2.5) + y = 7
5 + y = 7
y = 2

Answer:
For the first one about Jack the answer to A is 14, 21, 30 and for b the answer is 22. Now for Maria the answer for A is 24 , 40 , 80 and for b it's 8
Step-by-step explanation:
All you had to do for Jack was just add 10 to each number that's for A Now for B you just had to minus ( - ) 10 from 32 which equals 22. For Maria You needed to times ( × ) every number from 4 .
Step-by-step explanation:
option b ie. 98 degree
if you do angle 2 +10x+8=180
from 10x +8 and 12x -10 we can get the value of X
