Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
Answer:
38/100
Step-by-step explanation:
To combine the amounts, add the fractions with a common denominator.
3/10 kilogram flour is 30/100.
8/100 kilogram of sugar.
Both now have the same denominator. Add the numerators to find the total.
30/100 + 8/100 = 38/100
