Question 137394
4x = 8
5y = 15

4x/4 = 8/4
x = 2

5y = 15
5y/5 = 15/5
y = 3


0.2(6.3) + 0.4(6.3) = 1.7(6.3)
8.3(0.4) – 6.3(0.4) = -4.3(0.4)

 1.26x + 2.52y = 10.71
+3.32x – 2.52y = -1.72
 4.58x         = 8.99
	 
4.58x/4.58 = 8.99/4.58
x = 1.96

0.2(1.96) + 0.4y = 1.7
0.392 + 0.4y - 0.392 = 1.7 – 0.392
0.4y/0.4 = 1.7/0.4
y = 3.25
