Answer :
Answer:
(4,2)
Step-by-step explanation:
-3x+5y=-2
3x+7y=26
I will add the two equations to eliminate x
-3x+5y=-2
3x+7y=26
---------------------
0x + 12y = 24
Divide by 12
12y/12 = 24/12
y =2
Now find x
3x+7y =26
3x+7*2 =26
3x+14= 26
Subtract 14 from each side
3x+14-14 =26-14
3x= 12
Divide by 3
3x/3 =12/3
x=4
Answer:
found:
x=−3
y=5
Explanation:
I would multiply the first equation by −4 and the second by 3 and add together the two equatins (in columns):
{−12x−28y=−104
{12x+15y=39
0−13y=−65
So: y=6513=5
Substitute back this value into the first equation:
3x+7⋅5=26
3x=26−35=−9
x=−93=−3
Step-by-step explanation:
Its second
