8x + 6y = 3, 6x-4y = 5?

8x + 6y = 3, 6x-4y = 5?

8x+6y=3,①
6x-4y=5 ②
① We get 16x + 12Y = 6
② We get 18x-12y = 15
Add up to get 34x = 21
The solution is x = 21 / 34
Bring in and get
63/17 -4y=5
4y=-22/17
y=-11/34
∴ x=21/34,y=-11/34

The solution equation is: 8x - 4.5 △ 0.2 = 163 (x + 30) = 6x + 303 - (5-2x) = x + 2
73x-(67-84x）-14=76 15-（7-5X）=2X（11-3X) X+(X+10)+(x+8)=36×3 11×（4-x)+15×（4-X）=30

73x-(67-84x）-14=76 73x-(67-84x)=76+14 73x=90+67-84x 73x+84x=157 157x=157 x=1

4.8x-2x = 5.6
x÷3.6=3

4.8x-2x=5.6
2.8x=5.6
x=2
x÷3.6=3
x=3.6×3
x=10.8
