Solve this using Substitution. <br> {y=x+1 <br> {2x+y=7

Elina [12.6K]

Y = x + 1....so we sub in x + 1 for y in the other equation

2x + y = 7
2x + x + 1 = 7 ....combine like terms
3x + 1 = 7....subtract 1 from both sides
3x = 7 - 1
3x = 6 ....divide both sides by 3
x = 6/3
x = 2

y = x + 1
y = 2 + 1
y = 3

so ur solution is : (2,3)

There are 3 ladies for every 2 men qt a party if there are 40 men at the party how many ladies are at the party . show your work

Lynna [10]

Ok so the constant is 3:2 so if we do x for women then it would be x:40. To find x we do 40/2 which is 20 so then you multiply 20 to 3 to get the amount of women for every 40 men which is 60 women
B)60
40:60
