Hello!
We put y into the second equation
2x -1(3x - 26) = 19
Distribute the -1
2x - 3x + 26 = 19
Combine like terms
-x + 26 = 19
Subtract 26 from both sides
-x = -7
Since x is negative we can multiply both sides by -1 to make it positive
x = 7
Now we put this into the first equation to find y
y = 3(7) - 26
Multiply
y = 21 - 26
Subtract
y = -5
The answer is -5
Hope this helps!
Answer:
23
Step-by-step explanation:
we know that it is an odd number because an even number added to 5 would equal an odd number (i.e. 5+6= 11), while an odd number added to 5 would be even (i.e. 5+1=6). then we can guess & check to discover that 23/22 = 1 with a remainder of 1.
The answer would be 5.5854586e+17
Answer: x=500
Step-by-step explanation:
Twenty more (+20) of a fifth of a number (.2x) is equal to 120. So, the equation would be .2x+20=120. To isolate x, subtract 20 from each side. So now we have .2x=100. To get rid of the .2 or 1/5, we have to multiply everything by the reciprocal of 1/5, or 5. So, 100(5)=.2x(5), or simplified, x=500. Hope this helps!
