Question

.8x + 5y = 9
3x + 26 = 4

Solve it by cross multiplication method.
​

Answer 1

Step-by-step explanation:

Cross multiplication isn't possible for sums like this

We should do by substituting

3x+26=4

3x=4-26

3x= -22

x=-22/3

Let's solve for y

8x+5y=9

8(-22/3)+5y=9

-176/3 +5y =9

5y=9-(-176/3)

5y=9+(176/3)

5y= 203/3

y= 203/3/5

y=203/15
