Answer:
y = 18
a = -2
Step-by-step explanation:
Hello There!
For the first one we need to create an equation to solve for y
23+7=y+12
30=y+12
isolate the variable using inverse operations
subtract 12 from each side
30-12=18
we're left with y = 18
for the second one we need to create an equation to solve for a
3+15+a=8+8+8
3+15=18
8+8+8=16
16=18+a
step 1 subtract each side by 18
16-18=-2
we're left with a = -2
If you add the two equations together,
Ex:
-3x-4y=2
+ 3x+4y=-3
————————
0=-1
So there is no solution
E2x-3=7 (multiply by ln e on both sides)
ln e of e=1
>>> 2x-3=ln 7
x=(ln 7 + 3)/2
x=2.47 (to 3 s.f)
