Answer:
Step-by-step explanation:
2x-6y=2
....(1)
-4x+8y=-8....(2)
divid the equation (2) by : - 2 x +4y = - 4...(3)
add (1) and (3 ) :2x-6y - 2 x +4y =2-4
-2y=-2
y = 1
put y=1 in (1) : 2x-6(1)=2
2x=8
x =4
Answer:
Step-by-step explanation:
First move the numbers from the Left hand side to the right hand side. To do so, as it is an equation i.e. both sides must remain the same, you add or subtract the same numbers on both side.
5 + 13k - 61 = 17
5 - 5 + 13k - 61 + 61 = 17 - 5 + 61
13k = 73
k = 73 / 13
k = 5.62 (approximately)
