Solve simultaneously using sub method y=3-2x and y=3x+1

Mathematics
1 answer:
Kay [80]4 years ago
8 0

Answer:x=0.4 y=2.2

Step-by-step explanation:

Y=3-2x and y=3x+1

Substitute

3-2x=3x+1

Collect like terms

3-1=3x+2x

2=5x

Divide both sides by 5

2/5=5x/5

X=2/5=0.4

Substitute x=0.4 in y=3-2x

Y=3-2(0.4)

Y=3-0.8

Y=2.2

9.973 rounded to the nearest hundredth
DaniilM [7]

The hundredths place is the second digit to the right of the decimal point. In this case, it's 7. When rounding, we want to look at the number in the thousandths place, or 3.

If the number is 0 to 4, you round the hundredths digit down to remain the same. If the thousandths digit is 5 to 9, you round up a number.

In this case, since the number is 3, we just keep 7 the same. So, the answer would be:

9.97
