The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.
EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.
5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x
4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y
10(4x + 5)= (10*4x) + (10*5)= 40x + 50
ANSWER:
Only one pair below is needed for your answer.
5(2 + 3x)= 7 + 15x
4(2x + 4y)= 8x + 16y
10(4x + 5)= 40x + 50
Hope this helps! :)

Answer:
x = 2, y = 3
Step-by-step explanation:
x - 3y = - 7 → (1)
x = 5 - y → (2)
Substitute x = 5 - y into (1)
5 - y - 3y = - 7
5 - 4y = - 7 ( subtract 5 from both sides )
- 4y = - 12 ( divide both sides by - 4 )
y = 3
Substitute y = 3 into (2)
x = 5 - 3 = 2
solution is (2, 3 )
