-35x+70y=29
10x-20y=-10

x=3

y=2

Step-by-step explanation:

you can either use substitution or elimination method

I find substitution method better

substitute x with 3 and in this method u use one of the equation

10(2)-20y=-10

20-20y=-10=2

y=2

now use y=2 with the same equation

10x-40=-10=30

10x=30

x=3

therefore

x=3

y=2

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

answer: ok
