2x+2=-52
2x=-54
x=-27
That is the simple formula for it.
Answer:
24, 14
Step-by-step explanation:
x + y = 38
x = 10 + y
You can substitute (10+y) into the top equation where the x is.
10 + y + y = 38
10 + 2y = 38
2y = 28
y = 14
Now plug 14 in for y in either equation to get x
x = 10 + 14
x = 24
Area= base + base / 2 then multiply the height.
Example: 6+7 /2*6= 39
Answer:
y=mx+b
Step-by-step explanation:
m=3
b=3
y=3x+3
Answer: the answer is 2x-3=15
Step-by-step explanation: It’s simple so whenever you see x in the equation you just plug 9 in it’s place for example:
equation 1: 2x-3=15 —> 2(9)=18-3= 15 for this equation 9 is the solution
equation 2: 4+5(9)=18 —> 4+45=49 and 49 does NOT equal to 18 therefor 9 is not a solution
equation 3: 3(9)+2= 29 and 29 does NOT equal to 25 so 9 is not the solution
equation 4: 81(9)-3=6 —> 726 does NOT equal to 6 so not a solution
equation 5: 24-2(9)=13–> 6 does not equal to 13 so 9 is not a solution
equation 6: 3(9)+7=8 —> 34 does not equal to 8 so 9 is not a solution
(hope this helps)
