Question

2x-4y=10;10x+2y=12 slove the simulations equation​

Answer 1

Answer:

Use equation (1) to express x in terms of y

x=y+1

Substitute x into equation (2) and solve for y

335∴y=y−2(y+1)=y−2y−2=−y=−5

Substitute y back into equation (1) and solve for x

x∴x=(−5)+1=−4

Check the solution by substituting the answers back into both original equations

Write the final answer

xy=−4=−5
