What is the x and y to 3y+7x=4 -6x+y=-7

x=1 and y=-1

Step-by-step explanation:

Lets name the equations as

3y+7x=4 or 7x+3y-4=0eq(1)

-6x+y=-7 or -6x+y+7=0eq(2)

multiplying eq(2) with 3 and subtracting eq(1) from eq(2)

(-6x+y+7=0)*3

(-18x+3y+21)-(7x+3y-4) =0

we can write it as

-18x+3y+21-7x-3y+4=0

-25x + 25=0

-25x=-25

x=1

plugging the value of x in eq(1)

7*1+3y-4=0

7+3y-4=0

3y+3=0

3y=-3

y=-1

so x=1 and y=-1

a² + b²= c²

24² + 7² = c²

c= 25

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
