<u>The solution is (1,2)</u>
Step-by-step explanation:
7x + 10y = 27
x - 10y = -19 +--------------------
8x = 8
Divide by 8 on both sides
x = 1
To find y substitute any of the equations to 1
7(1) + 10y = 27
7 + 10y = 27
Substract 7 from both sides
10y = 20
Divide by 10
y = 2
Answer:
False
Step-by-step explanation:
3 and 3 add up
6,2,12 and 4 add up
But 9 and 7 don’t it should be like 9 and 18
Oooo ok
I don’t now true this or no
But answer is 13
