make five separate math multistep equations with words

1) The sum of three times a number and four times another number is twenty. Find the two numbers.

Equation: 3x + 4y = 20

2) Mary is three years older than twice John's age. If the sum of their ages is 35, how old is Mary?
Equation: M = 2J + 3 and M + J = 35

3) A rectangular swimming pool has a length that is 10 meters longer than its width. The perimeter of the pool is 80 meters. Find the dimensions of the pool.
Equation: 2L + 2W = 80 and L = W + 10

4) A shop sells shirts for $15 each and pants for $25 each. If the total cost of 5 shirts and 3 pants is $145, find the cost of one shirt and one pair of pants.
Equation: 5S + 3P = 145 and S = 15 and P = 25

5) The sum of two consecutive even integers is 46. Find the two integers.
Equation: n + (n+2) = 46
