Steps to problems
1.
6x - 2y = 18
+ -6x + 7y = -3
5y = 15
y = 3
6x- 2(3) = 18
6x - 6 = 18
6x = 24
x = 4
+ -6x + 7y = -3
5y = 15
y = 3
6x- 2(3) = 18
6x - 6 = 18
6x = 24
x = 4
2.5x + 2y = 48
3x + 2y = 32
subtracting gives: 2x = 16
and divide 2x to both sides and then your answer will be ....
3.2x + y = 8
-x + y = 2
subtract:
3x = 6
And fror y
3x = 6
x = 2
2(2) + y = 8
4 + y = 8
4.
3x + 2y = 32
subtracting gives: 2x = 16
and divide 2x to both sides and then your answer will be ....
3.2x + y = 8
-x + y = 2
subtract:
3x = 6
And fror y
3x = 6
x = 2
2(2) + y = 8
4 + y = 8
