Answer:
X = 1
Y = 5
Step-by-step explanation:
we have to figure out what x and y = that make both answers correct
3 x 1 = 3
3 + 5 = 8
That means that the first equation is right with X = 1 and Y = 5
Let's see the second equation
5 x 1 = 5
5 + 5 = 10
That means both equations are right so the answer would be
X = 1 and
Y = 5
Answer: #20, x = 3
#21, x = 1/2
Step-by-step explanation:
#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1
3x + 11 = 4x + 8
<u>-3x -3x</u>
11= x + 8
<u> - 8 - 8</u>
3 = x
#21) 12x(5) = 6x + 9 + x + 10 + x + 7
60x =8x + 26
<u> -8x -8x</u>
52x = 26
divide both sides by 52
x = 1/2
