Answer:
x=3 y=4
Step-by-step explanation:
x+y=7; x + 2y =11
step: solve x + y = 7 for x:
x + y+ -y =7 + -y (add -y to both sides)
x = -y + 7
step: substitute -y + 7 for x in x + 2y =11:
x + 2y = 11
-y + 7 + 2y = 11
y + 7 =11(simplify both sides of the equation)
y + 7 + -7 = 11 + -7 (add -7 to both sides)
y = 4
step: substitute 4 for y in x = -y + 7:
x = -y +7
x = -4 + 7
x = 3 (simplify both sides of the equation)
Answer:
8
Step-by-step explanation:
5 and 1/3 is also 16/3. Then, 2x8 equals 16
First we have to find out how many cups equals one quart
There are 4 cups in one quart
so simply multiply
4*372= 1488
So there are 1488 cups in 372 quarts
First multiply 2x - 5 by 3 amd will open the brackets
3(2x-5)-4=33
6x - 15 - 4 = 33
6x - 19 = 33
Take -19 to other side and its sign will be become +
6x = 33 + 19
6x = 52
x = 8.6
