I think u should check the first one again u made a mistake but the second one is correct if u need any more help ask me
Answer:
I will go for a part the rest You can do by yourself
Step-by-step explanation:
Multiply the second equation to get same amount of x in both equations
2x=2-3y/2
multiply both equations by 2 to get rid of the fraction in second equation
4x+14y=34
4x=4-3y
subtract equation(2) from equation(1)
14y=30+3y
11y=30
y=30/11, x=-23/22
Answer:
O 3+(-1)
Step-by-step explanation:
Answer:
X = 105
Step-by-step explanation:
<u>2x</u> = 42
5
Multiply both sides by 5
5 × <u>2x</u> = 5×42
5
5 cancle 5
2x = 5 × 42
2x = 210
Divide both sides by 2
<u>2x</u> = <u>210</u>
2 2
x = 105
There are several ways to turn a fraction into a decimal but one way is to divide the numerator by the denominator
In
, you divide 8 by 10
8÷10=.80
Get the whole number 5 and add it to .80
5+.80=5.80
5.80 is your answer
