Hello from MrBillDoesMath!
Answer:
x = 19, y = 36
Discussion:
x + 3 = 22 (*)
2x - y = 2 (**)
Subtract 3 from both sides of (*)
x + 3 -3 = 22 = 3 = 19 =>
x = 19
Substitute x= 19 in (**)
2(19) - y = 2 =>
38 - y = 2 => (add y to both sides)
38 -y + y = 2 + y =>
38 = 2 + y => (subtract 2 from both sides)
38 -2 = 2 -2 + y =>
36 = y

Answer:
x = 6
Step-by-step explanation:
To find x we set up an equation as so:
Then we solve by multiplying 4.5 by 8 and 6 by x
Solve for x
x = 6
To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number
when divided both equals 0.75
3x+250-100×2x = 24.5x to 2nd power.
Got this same question earlier in the year.
